Abstract Benefiting from similar hydrogen bonding energy to Pt and much lower price compare with Pt, Ru based catalysts are promising candidates for electrocatalytic evolution reaction (HER). The catalytic activity of nanoparticles can be enhanced through improving their dispersion by using different supports, the strong metal supports interaction further regulate performance. In addition, single‐atom (SACs) almost 100% atomic utilization attract great attention coordinative atmosphere single atoms adjusted supports. Moreover, syngenetic effects improve performance catalysts. this review, progress HER electrocatalysts summarized according existing forms, including (NPs), (SAs) combination both NPs SAs. common such as carbon materials, oxides, phosphides sulfides classified clarify active centers. Especially, possible mechanisms reasons improved discussed experimental results theoretical calculations. Finally, some challenges opportunities prospected facilitate development HER.

Abstract Photocatalytic N 2 reduction to ammonia rises as a cost‐effective, environmentally benign, and efficient route generate transportable/storable energy carrier essential fertilizer. Recently, photocatalysts anchored with various atomically scattered active centers (ASACs), such Ru, Fe, Au, Pt, Cu, Mo, La, are extensively explored in photocatalytic ‐to‐ammonia transformation. This review critically summarizes the current achievements synthesis of photocatalyst supports (such metal oxide, carbon nitride, metal‐organic framework, covalent organic framework) above‐mentioned ASACs for form ammonia. The routes, structural/compositional characteristics, performances these summarized introduced. Furthermore, atomic‐scale relationship between structure/composition performance is also reaction mechanism including kinetics/thermodynamics, pathways, charge kinetics, especially those revealed by state‐of‐art characterization techniques, have been highlighted. outlines basic principles novel aimed at evolution. Finally, challenges, opportunities, future outlooks evolution

Abstract Hydrogen energy is essential to establishing a sustainable and reliable system. The continuously growing demand for hydrogen driven by the challenges associated with greenhouse gas emissions resource depletion. This paper investigates summarizes some intriguing production processes that have evolved from laboratory stages mature commercial applications. analysis of techno-economic, environmental effects investment trends these are included. Currently, dominantly produced methods fossil fuels as feed. These technology relatively account majority world's production, around 99%. However, results in significant carbon emissions. Around 1400 million tons dioxide emitted into atmosphere. To achieve neutral strategy, hydrocarbon needs become clean. Equipping capture, utilization, storage system promising way reduce In addition, schemes zero like electrolytic photocatalysis attracting increasing attention. survey suggest price addition capture equipment ranges 1.47 6.04 USD/kg, which higher than value without additional facility (1.03–2.08 USD/kg). introduction tax expected narrow cost gap between two. Besides, electrolysis remains expensive (6.25–12.2 USD/kg), depending on source cell equipment. high-pressure autothermal reforming technique coupled powered renewable favored global investment. Finally, key opportunities clean discussed this paper. More attention should be paid catalyst blockage or deactivation fuel production. For new zero-carbon method, designing efficient, economical catalysts materials its large-scale application.

Designing a heterostructure nanoscale catalytic site to facilitate N2 adsorption and photogenerated electron transfer would maximize the potential for photocatalytic activity reduction reactions. Herein, we have explored interfacial TiO2 nanograins between Ti3C2TxMXene-WS2 addressed beneficial active sites expand effective charge rate promote sonophotocatalytic fixation. Benefiting from contact dual interface maximizes carrier separation WS2 MXene/TiO2. The of MXene@TiO2/WS2 hybrid, which was assessed by examining photoreduction with ultrasonic irradiation, much higher than that either sonocatalytic because synergistic effect under photoirradiation. Schottky junction MXene on hybrid MXene/TiO2-WS2 resulted in performance through transfer, is 1.47 1.24 times greater MXene-WS2 nitrogen fixation pollutant degradation, respectively.

Hydrogen carriers are one of the keys to success using hydrogen as an energy vector. Indeed, sustainable production exploits excess renewable sources, after which temporary storage is required. The conventional approaches and transport compressed (CH2) liquefied (LH2), require severe operating conditions related pressure (300–700 bar) temperature (T < −252 °C), respectively. To overcome these issues, have hindered market penetration, several alternatives been proposed in last few decades. In this review, most promising (ammonia, methanol, liquid organic carriers, metal hydrides) considered, main stages their supply chain (production, storage, transportation, H2 release, recyclability) described critically analyzed, focusing on latest results available literature, highlighting our current concern. section reviews recent techno-economic analyses drive selection carrier systems constraints that must be considered. analyzed show how a multiparametric function, it depends technological factors well international policies regulations.

The performance of BiOBr in photocatalytic nitrogen (N2) fixation is suboptimal, attributed to the weak chemisorption and activation N2 by surface atoms. In our study, we achieved formation two-dimensional (2D) bismuth (Bi) on nanosheets through situ annealing hydrogen atmosphere successfully constructed a unique 2D-2D Bi/BiOBr ohmic heterojunction using one-step method. Notably, was utilized for under visible light (λ > 400 nm) ultrapure water, demonstrating an exceptional rate 376.16 μmol g–1 h–1. This 7.7 4.1 times higher than those BiOBr-OVs, respectively. improved efficiency significantly enhanced adsorption capability more effective separation photogenerated carriers, both stemming from distinctive 2D/2D architecture heterojunction. work demonstrates that 2D Bi offers active sites facilitate introduces approach design construction photocatalysts applications spanning catalysis, optoelectronics, electronics, beyond.
