Summary: In this study, a heterogeneous catalyst was prepared by combining immobilized iron trinitrophthalocyanine with oxidic biochar derived from Flueggea suffruticosa residue, and it was used for the removal of tetracycline. The distribution of iron trinitrophthalocyanine on the surface of oxidic biochar increased the catalytic activity of hydrogen peroxide, resulting in a 51.6% removal of tetracycline after 60 minutes. The catalytic process involved the oxidation of tetracycline into small molecule compounds through demethylation, ring opening, hydrogenation, and other steps.

Summary: In this study, supported carbon molecular sieve (CMS) membranes were prepared using wood tar as the precursor and a new porous carbon fiber (PCF) as the support. The CMS membrane supported on PCF exhibited higher gas permeance and selectivity compared to membranes supported on commercially available porous ceramic tubes (NA3). The study demonstrated the high potential of PCF as a support for CMS membranes in hydrogen separation applications.

Summary: Defects engineering was utilized to tune the catalytic performance of heterogeneous catalysts by modulating the surface electronic structure and creating more active sites. In this work, porous Co-Mn oxide nanosheets with abundant oxygen vacancies were prepared, and the oxygen vacancies were found to enhance O-2 absorption and activation, resulting in improved oxidase-like activity. A colorimetric sensing platform for heparin detection was established based on the inhibition effect of heparin on the oxidase-like activity of the nanosheets. This study provides a high-performance non-precious metal oxidase mimic and a sensitive colorimetric method for heparin detection.
