The remarkable effect of an unsupported nanoporous gold catalyst (AuNPore) on chemoselective hydrogenation of α,β-unsaturated aldehydes using silane has been described. Enals can be reduced with excellent selectivity, giving the corresponding allylic alcohols in good to high chemical yields.

The high cost of noble metal nanoparticles used for catalytic reduction of 4-nitrophenol (4-NP) leads to an extensive study of Ni nanoparticles (NPs) for their low cost and magnetic properties. However, the conventional routes for preparing the ferromagnetic Ni NPs usually lead to large particle ...

The hexavalent chromium contained in wastewater of some industries is toxic to most microorganisms and potentially harmful to human health. The application of photochemical reduction of Cr(VI) in the treatment of wastewater from the electroplating industry was studied, and a continuous reactor in ...

Oxidation (off state) and reduction (on state) of a single azurin molecule is monitored, one electron at a time, which depend on the chemical redox potential. By analysing the fluorescence time traces from individual azurin molecules, reaction kinetics and redox thermodynamics were determined.

Borohydrides are an important class of reagents in both organic and inorganic chemistry. Though popular as hydride-transfer reagents for reduction, since earlier work from the 1970s, borohydride reagents have also been known to serve as hydrogen-transfer reagents. In pursuit of greener tin ...

Converting solar energy into valuable hydrogen and hydrocarbon fuels through photocatalytic water splitting and CO2 photo-reduction is highly promising in addressing the growing demand for renewable and clean energy resources. Developing efficient photocatalysts for solar-driven H2 production and ...

KCaSrTa5O15 with tungsten bronze structure and a band gap of 4.1 eV showed activity for water splitting without cocatalysts. The activity was improved by loading the NiO cocatalyst. The apparent quantum yield of optimized NiO-loaded KCaSrTa5O15 was 2.3% at 254 nm for water splitting. When CO2 gas ...
