Summary: Pre-treating graphite sheets in a H2SO4/H2O2 solution before electro-exfoliation can lead to easier and faster exfoliation of graphite. Control of the H2SO4 : H2O2 volume fraction in the pre-treatment solution is crucial for achieving optimal exfoliation degree and excellent electrochemical properties in the resulting exfoliated graphite.

Summary: This study investigates the adsorption of sulfadiazine (SDZ) by biochars prepared at different temperatures and explores the connection between their chemical properties and adsorption capacities. The results show that higher pyrolytic temperature and certain chemical properties of biochar significantly improve its adsorption capacity for SDZ. The study also introduces the lateral size (La) of aromatic clusters in biochar as an effective indicator for predicting the adsorption capacity of graphite-like biochar. Furthermore, density functional theory calculations reveal that larger aromatic clusters accommodate more SDZ molecules, increasing their binding energy with biochar. These findings provide valuable information for designing efficient biochar adsorbents in the future.

Summary: Improving catalytic efficiency for the oxygen reduction reaction in electrode reactions of fuel cells and metal-air batteries is crucial, with heteroatom doping and structural optimization being efficient strategies. The designed B-N-3 structure in carbon, inspired by transition metal M-N-x sites, shows promising oxygen reduction catalytic performance in alkaline media. Ordered macroporous structures and B/N co-doping enhance the activity of metal-free materials for oxygen reduction, providing new insights into the design of nonmetallic ORR electrocatalysts.
