A standalone bismuth vanadate-silicon artificial leaf achieving 8.4% efficiency for hydrogen production

Nature Communications, Journal Year: 2025, Volume and Issue: 16(1)

Published: March 21, 2025

Abstract The development of scalable photoelectrochemical water splitting with high solar-to-hydrogen efficiency and long-term stability is essential while challenging for practical application. Here, we design a BiVO 4 photoanode gradient distributed oxygen vacancies, which induces strong dipole fields to promote charge separation. Growing sea-urchin-like FeOOH cocatalyst on the leads photocurrent density 7.0 mA cm −2 at 1.23 V versus reversible hydrogen electrode stable over 520 h under AM 1.5 G illumination. By integrating silicon photovoltaic cell, standalone artificial leaf achieves 8.4%. scale-up these leaves up 441 2 in size can deliver 2.7% natural sunlight. Life cycle assessment analysis shows that solar has little environmental footprint production. Our study demonstrates possibility designing metal oxide-based

Cobalt-Doped Porous Carbon Protection Layer for Bismuth Vanadate Photoanodes with Enhanced Stability in Photoelectrochemical Water Splitting

ACS Applied Energy Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 27, 2025

Photoelectrochemical water splitting by bismuth vanadate (BiVO4) photoanodes is a promising strategy for clean hydrogen production. However, poor stability caused direct exposure to the electrolyte one of great obstacles hinder its application. Herein, cobalt-doped dopamine-derived porous carbon layer designed as an efficient and low-cost protection BiVO4 photoanodes. The thick around 10 nm can prevent from electrolyte. electrical conductivity structure guarantee charge mass transfer within layer. As result, obtained photoanode coated exhibits enhanced photocurrent density 4.78 mA/cm2 at 1.23 V vs reversible electrode stability.

BiFeO₃ as a Next‐Generation Photocatalyst: Bridging Material Design with Environmental Remediation

ChemPhysChem, Journal Year: 2025, Volume and Issue: unknown

Published: March 4, 2025

Bismuth ferrite (BiFeO₃) is a multiferroic perovskite material with narrow band gap (~2.1 eV), demonstrating significant potential as photocatalyst for environmental remediation and sustainable energy applications. Its photocatalytic capabilities include dye degradation, air purification, wastewater treatment, hydrogen generation, all driven by its ability to harness visible light. This review critically examines the factors influencing performance of BiFeO₃ (BFO) doped derivatives. Advances in synthesis techniques, such sol-gel, hydrothermal, combustion methods, are discussed concerning particle size, crystallinity, surface modifications. Key strategies, including rare earth element doping, heterostructure formation, co-catalyst integration, explored their role enhancing charge separation light absorption, achieving efficiency improvements over 90 % some cases. The mechanistic pathways photocatalysis, focus on electron-hole dynamics radical analyzed provide deeper insights into performance. Despite potential, challenges limited stability rapid recombination rates persist. identifies critical research gaps proposes directions optimizing BFO's design scalability, reinforcing relevance next-generation addressing global challenges.
