Semiconductor-Based Photoelectrocatalysts in Water Splitting: From the Basics to Mechanistic Insights—A Brief Review

Materials, Journal Year: 2025, Volume and Issue: 18(9), P. 1952 - 1952

Hydrogen and oxygen serve as energy carriers that can ease the transition of due to their high densities. Nonetheless, production processes entail development efficient low-cost storage conversion technologies. In this regard, photoelectrocatalysts are materials based on photoelectronic effect where electrons holes interact with H2O, producing H2 O2, in some cases, is achieved acceptable efficiency. Although there several reviews topic, most them focus traditional semiconductors, such TiO2 ZnO, neglecting others, those non-noble metals organic ones. Herein, semiconductors like CdSe, NiWO4, Fe2O3, others have been investigated compared terms photocurrent density, band gap, charge transfer resistance. addition, brief review aims discuss mechanisms overall water-splitting reactions from a photonic point view subsequently discusses engineering material synthesis. Advanced composites also addressed, WO3/BiVO4/Cu2O CN-FeNiOOH-CoOOH, which demonstrate efficiency by delivering densities 5 mAcm−2 3.5 mA cm−2 at 1.23 vs. RHE, respectively. Finally, authors offer perspectives list main challenges experience developing semiconductor-based applied fields. manner, provides advances these topics, used references for new directions designing active photoelectrocatalytic water splitting.

The emerging role of biomass in complementing a renewable energy portfolio: A Review

BioResources, Journal Year: 2025, Volume and Issue: 20(3)

Published: May 30, 2025

Plant materials throughout the world, i.e. biomass, can provide annually roughly 18 x 1015 Watt-hours (6.5 1013 MJ) of energy, considering just residues from agriculture and forestry. However, at least part that amount has higher-valued uses, including being made into durable products, thereby keeping their carbon content contributing to global warming. This review considers circumstances under which it may be advantageous use biomass resources, either alone or in combination with other renewable energy technologies – such as solar wind meet society’s needs, especially for electricity, heating, transportation. There is a rapidly expanding pool published research this area. To slow climate change, rapid maturation most promising needed, followed by widespread early implementation. Of particular interest are synergistic combinations technologies, together way hydrogen, electricity. Another need make high-energy-density liquid fuels, aviation diesel, naphtha. Although some proposed schemes complicated, expected gradually implemented growing component installed capacity coming years.
