Article Abstract
We report the synthesis of bell-shaped Bi/BiSBr metal/semiconductor heterostructures as a photocatalyst based on nontoxic and Earth-abundant elements. Their unique morphology arises from a multistep growth process, involving (1) the nucleation of BiSBr nanorods, (2) the reduction of a metallic-Bi domain on their surface induced by -didodecylmethylamine, and (3) the heterostructure accretion by a localized reaction at the Bi/BiSBr interface promoted by Ostwald ripening. These heterostructures display remarkable stability in polar solvents, remaining almost unaffected by prolonged exposure to isopropanol and water, and exhibit high photocatalytic efficiency for the degradation of organic dyes (i.e., Rhodamine B and Methylene Blue) under visible-light irradiation, with good recyclability. Additionally, preliminary tests demonstrate CO reduction capabilities, which make these heterostructures promising for both the photocatalytic degradation of pollutants and photoelectrochemical CO conversion. The straightforward synthesis process and the use of nontoxic and Earth-abundant elements offer significant potential for sustainable energy conversion technologies.

Tin sulfide (SnS) is a promising earth-abundant and non-toxic material for photovoltaic applications; however, its practical use has been hindered by difficulties in achieving both stoichiometric composition and large grain sizes in thin films-factors critical for improving device performance. This study presents a unique strategy for fabricating high-quality SnS thin films with controlled stoichiometry and micron-scale grains using a metallic tin target and sulfur plasma (S-plasma). Unlike conventional approaches that rely on toxic H₂S gas, this method employs a S-plasma to enhance sulfur reactivity and mitigate sulfur deficiencies during film deposition.

We report an unprecedented iron-catalyzed C-H alkylation of widespread benzamides using readily available allenes. The method, based on cheap, nontoxic, and earth abundant iron catalysts, exploits the assistance of removable triazole directing groups to yield a wide array of internal olefins, even at room temperature, with excellent stereocontrol, good yields, and broad functional group tolerance.

Herein, we report that Celite (diatomaceous earth) commonly viewed as an innocent filter aid or support material, or Earth-abundant, non-toxic metal oxides are efficient mechanoactivated catalysts for arene and heteroarene C─H bond radical trifluoromethylation and pentafluoroethylation, with the activity comparable with previously reported mechanochemical methods utilizing piezoelectric materials. Celite was also applied for mechanochemical dibromination of a double bond with N-bromosuccinimide, eliminating the need to use of lithium titanate as a piezoelectric mechanoredox catalyst. Mechanoactivation via ball milling in the presence of minimal amount of solvent was crucial to observe the reactivity, while sonication or using a pre-ground suspension in a bulk solvent were not efficient.

Copper zinc tin sulfide (CuZnSnS, CZTS) is an eco-friendly, non-toxic, and cost-effective photocatalyst composed of earth-abundant elements, offering a tunable narrow band gap that is ideal for environmental remediation. In this study, CZTS photocatalyst powders with varying Cu:Zn ratios (1:2, 2:1, and 2.5:1) were synthesized using a rapid microwave-assisted method and evaluated for their effectiveness in degrading organic pollutants in water.
