Perovskites are bringing revolutionization in a various fields due to their exceptional properties and crystalline structure. Most specifically, halide perovskites (HPs), lead-free (LFHPs), perovskite quantum dots (HPs QDs) becoming hotspots unique optoelectronic properties, low cost, simple processing. HPs QDs, particular, have excellent photovoltaic applications because of tunable emission, high photoluminescence yield (PLQY), effective charge separation, cost. However, practical the QDs family some limitations such as degradation, instability, deep trap states within bandgap, structural inflexibility, scalability, inconsistent reproducibility, environmental concerns, which can be covered by encapsulating into porous materials like metal–organic frameworks (MOFs) or covalent–organic (COFs) that offer protection, prevention aggregation, optical flexibility structure, enhanced biocompatibility, improved stability under harsh conditions, consistency production quality, efficient separation. These advantages MOFs-COFs help harness full potential for applications. This review mainly consists three parts. The first portion discusses perovskites, dots. In second portion, we explore MOFs COFs. third particular emphasis is given thorough evaluation development QDs@MOFs-COFs based comprehensive investigations next-generation intended diverse technological applications, CO2 conversion, pollutant hydrogen generation, batteries, gas sensing, solar cells. Finally, this will open new gateway synthesis perovskite-based

Harnessing solar energy through photocatalysis has excellent potential for powering sustainable chemical production, supporting the United Nations' environmental goals. Single-atoms (SAs) dispersed on catalyst surfaces are gaining attention their highly active and durable nature. Metal-organic frameworks (MOFs) can provide enough reactive sites to sustain selectivity durability over time because of tunable channels functional groups. Owing organized structures, MOFs ideal platforms securing individual atoms promoting solar-driven reactions. Few reviews have, however, reflected possibility combining SAs produce potent photocatalysts that may clean fuels valuable chemicals. This review provides a general overview methods generate photocatalysts. The challenges associated with these MOF-based single-atom systems also critically examined. Their future development is discussed as continued refinement helps more fully leverage advantages boosting photocatalytic performances - turning sunlight into chemicals in manner supports development. Insights gained here could illuminate pathways toward realizing profound empower production driven by renewable energy.

Metal–organic frameworks (MOFs) have been used in triboelectric nanogenerators (TENGs) to improve the output performance because of their designability and great triboelectricity. However, there still lacks detailed systematic research about influence morphology MOFs outputs TENGs. Here, ZIF-67 particles with three different sizes were successfully prepared filled silk fibroin (SF) prepare composite films. TENGs composed ZIF-67/SF composites assembled tested. Results indicated that was very sensitive filler particle size mass ratios. Owing much higher charge-trapping property, smallest (500 nm) increased power density by 5 times value 144 μW cm–2. With enhanced density, based on films applied more widely for harvesting mechanical energy real life.

Next‐generation Li‐ion batteries are expected to exhibit superior energy and power density, along with extended cycle life. Ni‐rich high‐capacity layered nickel manganese cobalt oxide electrode materials (NMC) hold promise in achieving these objectives, despite facing challenges such as capacity fade due various degradation modes. Crack formation within NMC‐based cathode secondary particles, leading parasitic reactions the of inactive crystal structures, is a critical mechanism. Mechanical chemical further deteriorate lifetime. To mitigate issues, an artificial electrolyte interphase can be applied active material before battery cycling. While atomic layer deposition (ALD) has been extensively explored for coatings, molecular (MLD) offers complementary approach. When combined ALD, MLD enables flexible hybrid coatings that accommodate volume changes during operation. This study focuses on depositing ‐titanium terephthalate thin films via ALD‐MLD. The electrochemical evaluation demonstrates favorable lithium‐ion kinetics reduced decomposition. Overall, deposited through ALD‐MLD promising features protective high‐energy electrodes, offering potential contributions enhancement advanced technologies supporting growth EV stationary industries.

Contact-electro-catalysis (CEC) usually uses polymer dielectrics as its catalysts under mechanical stimulation conditions, which although has a decent catalytic dye degradation effect still warrants performance improvement. A carrier separation promotion strategy based on an internal electric field by polarization can effectively improve ferroelectric material in photocatalysis and piezocatalysis. Therefore, necessary process of CEC also be promoted is largely expected to theoretically. However, the enhancement not been achieved experiment yet, because difficulty building inert dielectric. Herein, polytetrafluoroethylene (PTFE) dielectric was charged through electret process, believed establish for proved KPFM, XPS, triboelectric nanogenerator voltage output analysis. The fastest rate methyl orange reached over 90% at 1.5 h, while hydroxyl free radical (•OH) yield PTFE nearly three times that original PTFE. Density functional theory (DFT) calculations verified potential barrier interatomic electron transfer between H2O reduced 37% field. used herein optimize catalyst provides base use other general plastics facilitates production easily prepared, recyclable, inexpensive promote large-scale pollutant via CEC.
