Hydrogen storage by liquid organic hydrogen carriers: Catalyst, renewable carrier, and technology – A review

Carbon Resources Conversion, Journal Year: 2023, Volume and Issue: 6(4), P. 334 - 351

Published: March 21, 2023

Hydrogen has attracted widespread attention as a carbon-neutral energy source, but developing efficient and safe hydrogen storage technologies remains huge challenge. Recently, liquid organic carriers (LOHCs) technology shown great potential for stable transport. This allows economical large-scale transoceanic transportation long-cycle storage. In particular, traditional liquids are derived from nonrenewable fossil fuels through costly refining procedures, resulting in unavoidable environmental contamination. Biomass holds promise the preparation of LOHCs due to its unique carbon-balance properties feasibility manufacture aromatic nitrogen-doped compounds. According recent studies, almost 100% conversion 92% yield benzene could be obtained advanced biomass technologies, showing preparing biomass-based LOHCs. Overall, present systems their applications introduced this review, technical paths summarized. Furthermore, paper provides an outlook on future development technology, focusing biomass-derived N-doped compounds

Parametric influence of process conditions on thermochemical techniques for biochar production: A state-of-the-art review

Journal of the Energy Institute, Journal Year: 2024, Volume and Issue: 113, P. 101559 - 101559

Biochar refers to the carbonaceous black solid residue product obtained from thermochemical decomposition of waste biomass typically under oxygen-limited environment. There are many methods for biochar production streams, prominent pyrolysis, torrefaction, and hydrothermal carbonization. However, yield properties depend mainly on process parameters, such as temperature, residence time, heating rate, gas environment, feedstock types, among others. This review provides current state-of-art in by assessing parametric influence conditions yields, properties, compositions across carbonization their variants. Furthermore, compares contrasts different techniques with respect mass energy at similar conditions. It was found that irrespective techniques, operating typically, 150–300 °C hydrothermal, 200–300 300–600 remain most influential parameter compositions. While char yields comparable various conversion they had strong effect properties. Woody crop residues dominant feedstocks studied due attractive bioenergy (volatile matter >80% ash content <15%). Lastly, slow pyrolysis is optimized technique a typical 25–50 wt%, carbon 30–70 wt% calorific value 10–30 MJ/kg 450 lignocellulosic biomass. Other critical findings have been summarised, perspectives future research were provided. Overall, assessment can serve directive tool selecting an ideal technology high quality production.

TiN as Radical Scavenger in Fe─N─C Aerogel Oxygen Reduction Catalyst for Durable Fuel Cell

Small, Journal Year: 2024, Volume and Issue: 20(30)

Published: Feb. 23, 2024

Abstract Fe─N─C is the most promising alternative to platinum‐based catalysts lower cost of proton‐exchange‐membrane fuel cell (PEMFC). However, deficient durability has hindered their application. Herein, a TiN‐doped (Fe─N─C/TiN) elaborately synthesized via sol–gel method for oxygen‐reduction reaction (ORR) in PEMFC. The interpenetrating network composed by and TiN can simultaneously eliminate free radical intermediates while maintaining high ORR activity. As result, H 2 O yields Fe─N─C/TiN are suppressed below 4%, ≈4 times than Fe─N─C, half‐wave potential only lost 15 mV after 30 kilo‐cycle accelerated test (ADT). In ─O assembled with Fe─N─C/TiN, it presents 980 mA cm −2 current density at 0.6 V, 880 mW peak power density, 17 voltage loss 0.80 A 10 ADT. experiment calculation results prove that strong adsorption interaction (such as *OH, *OOH, etc.), radicals scavenged subsequently. rational integration Fe single‐atom, scavenger, highly porous adequately utilize intrinsic advantages composite structure, enabling durable active Pt‐metal‐free catalyst
