Summary: The production of sustainable catalytic supports for palladium nanoparticles using biomass residues as raw materials was investigated. Two different solids, chitosan/cellulose film and corn stem biochar, were tested as catalytic supports for palladium nanoparticles in the Suzuki-Miyaura reaction. The developed catalytic systems proved to be efficient and sustainable, promoting the formation of target products and utilizing green reactants under environmentally appropriate conditions. The results presented in the manuscript are expected to contribute to the valorization of biomass and agro-industrial residues in the development of new catalysts for the chemical industry.

Summary: Diethylenetriamine pentaacetic acid (DTPA) functionalized modified corn stalk cellulose (DCS) was prepared and used for the adsorption of sulfamethoxazole (SMZ) wastewater in the presence of copper (Cu). DCS exhibited hydrophilic groups, larger contact space, and lower steric hindrance, compared to raw corn stalk cellulose (RCS). The adsorption amounts for Cu and SMZ in the binary system were 4.41 mg/g and 29.7 mg/g, respectively. DCS demonstrated good pH buffering capability, resistance to interfering ions, and excellent regeneration performance. Competitive adsorption and complexation synergy occurred between Cu, SMZ, and DCS. Density functional theory (DFT) calculations further explained the adsorption mechanism, showing that DCS had more SMZ adsorption sites and could provide additional adsorption sites for Cu or SMZ.

Summary: Materials with enzyme-like activities and proteolytic potential, such as the Hf6O8-based NU-1000 metal organic framework, are showing promise as robust and effective alternatives to natural enzymes. The Hf-MOF exhibited high selectivity in cleaving protein substrates and maintained hydrolytic activity efficiently. In comparison to the Zr-NU-1000, the Hf variant showed slightly slower reaction rates but greater stability and recyclability, attributed to intrinsic differences between Hf-IV and Zr-IV centers and the lower surface area of Hf-NU-1000.
