Ag/AgBr-grafted graphite-like carbon nitride (g-C₃N₄) was constructed by in situ photoreduction of AgBr/g-C₃N₄ hybrid prepared by using the deposition-precipitation method. Compared with bare g-C₃N₄ and Ag/AgBr nanoparticles, a 28-fold and 6-fold enhancement in the degradation rate toward rhodamine B is observed over the Ag/AgBr/g-C₃N₄ hybrid under visible light irradiation, respectively. This study provides new insight into the development of highly efficient and stable g-C₃N₄-based plasmonic photocatalysts and facilitates their practical applications in environmental issues.

Ten years ago, it was reported that hydroxynitrile lyase (HNL) from defatted almond meal shows catalytic promiscuity in the addition of cyanide to imines. Here we provide experimental evidence that this addition occurs in a non-enzymatic reaction, and two structurally different HNLs do not catalyse this reaction.

The electrocatalytic reduction of nitrate on platinum was studied in the presence of a large variety of p-block metal promoters, in perchloric and sulfuric acidic media. Tin is the most active promoter, yielding volatile reaction products such as nitrous oxide and nitric oxide. Density functional theory calculations indicate that tin hydroxide adsorbed on the platinum surface enhances the nitrate adsorption and thereby increases the reduction activity.
