Summary: This study presents an effective approach to enhance the electrocatalytic hydrogen evolution of MoS2 with the synergistic effect of rGO and NIR light. The optimized 0.2rGO-MoS2 composite exhibited enhanced activity in a wide pH range under NIR irradiation, without the need for noble metal addition. The electrocatalytic hydrogen evolution by 0.2rGO-MoS2 under NIR irradiation in both acidic and alkaline media was attributed to the Volmer-Heyrovsky mechanism, and the composite showed good reproducibility and durability after repeated cycles and continuous electrolysis.

Summary: In this study, it was discovered that sulfonothioated BODIPY can cleave a sulfonylthio group from the meso-methyl position with a 10-fold higher quantum yield than previously studied leaving groups. The photocleavage was observed in both solution and cells, and it led to the controlled release of H2Sn. Therefore, sulfonothioated BODIPY has potential applications in cell signaling, redox homeostasis, and metabolic regulation studies.

Summary: Supercapacitors, known for their high-power density, long lifespan, and low maintenance requirements, are becoming more common. Cobalt sulphide, nickel sulphide, and graphene oxide (CoS/NiS/GO) nanocomposites were developed for use in supercapacitors due to their low cost and superior electrochemical characteristics. Various analyses including X-ray diffractometry and microscopy were conducted to assess the purity and morphology of the materials. Tests showed that the CoS/NiS/GO electrode had significantly lower impedance and higher electrochemical performance compared to the GO electrode. The CoS/NiS/GO nanocomposite exhibited a high specific capacitance and long cycle life.

Summary: We synthesized dual-pore carbon nitride materials with different ethylenediamine to carbon tetrachloride ratios and potassium hydroxide as a chemical activator, using nanosilica as a hard template to tune the properties of the materials. The prepared carbon nitride adsorbents had a large surface area, great pore volume, and high nitrogen content. They exhibited exceptional adsorption capacity for CO2 and H2S, high selectivity, and excellent cyclic stability. The results suggest that these materials have great potential for various applications in separation processes, catalysis, capacitors, and energy storage.

Summary: This article investigates the characteristics and effects of multi-heteroatoms doped porous carbons in CO2 adsorption applications. The introduction of heteroatoms provides more active sites and develops the porous structure of activated carbons, resulting in diverse CO2 capture performances. The P-doped activated carbon (PAC) with low phosphorus content exhibits high CO2 uptake and selectivity, prominent cyclic regeneration capacity, high turnover frequency (TOF), and turnover number (TON) for commercial scale as well as fast kinetic adsorption. The density functional theory (DFT) method is used to reveal the adsorption mechanisms and electronic properties of the systems.

Summary: Efforts are being made to improve the efficiency of water-oil separation by enhancing the performance of g-C3N4 with the help of Zn(OH)(2). This study investigates the effect of porosity and surface defects on the removal of oil from oil-water mixtures using g-C3N4/Zn(OH)(2) nanocomposites with varying amounts of Zn(OH)(2). The results highlight the significant impact of oxygen-containing groups in the nanocomposite on the wettability behavior and water-removing separation performance. The g-C3N4/Zn(OH)(2) coated mesh demonstrates potential as a material for water-oil separation due to its higher adsorption energy for water compared to oil molecules.

Summary: This study aims to fill the research gap of using aromatic ligands in catalyst synthesis for catalytic aquathermolysis of heavy oil. The developed oil-soluble catalyst (Ni-OSC) using catechol as a novel ligand effectively interacts with heavy oil fractions, reducing the content of resin and asphaltene and increasing the amounts of saturated and aromatic hydrocarbons. GC-MS analysis revealed an increase in low molecular weight hydrocarbons and a higher concentration of alkanes and aromatic hydrocarbons in the presence of Ni-OSC, improving the quality and recovery of heavy oil.
