Charge Separation News Today

Using photoelectrochemical (PEC) water splitting to produce green hydrogen from solar energy is a potentially practical approach. Unfortunately, the slow water oxidation reaction and very low charge separation efficiency of contemporary PEC systems make them unsuitable for practical applications.

Hygroelectricity, harnessing power from humidity, is explored by researchers as an energy source with recent advancements.

Rational multiple-field coupling, component control, and microarchitectures design for utilization of multiform driving forces as well as benefiting charge-carrier separation and migration is considered to be an outstanding approach to improve water splitting efficiency for alleviating increasing environmental problems. Herein, a novel piezo-photoelectric catalyst, coaxial TiO2-BaTiO3-CuInS2 heterostructures, was designed for efficient hydrogen production, synergistically driven by mechanical fo...

Photocatalytic CO2 reduction into valuable fuel and chemical production has been regarded as a prospective strategy for tackling with the issues of the increasing of greenhouse gases and shortage of sustainable energy. A composite photocatalysis system employing a semiconductor enriched with oxygen vacancy and coupled with metallic cocatalyst can facilitate charge separation and transfer electrons. In this work, mesoporous TiO2 and titanium-based perovskite oxides (BaTiO3 and SrTiO3) nanoparticl...
