Waste biomass-assisted synthesis of TiO2 and N/O-contained graphene-like biochar composites for enhanced adsorptive and photocatalytic performances

Spent-coffee grounds-derived biochar-supported heterogeneous photocatalyst: a performance evaluation and mechanistic approach for the degradation of pentachlorophenol

“…2923, 1742, and 1158 cm −1 are due to saturated C–H, CO, and C–O bonds, respectively. 29,30 Other small peaks in the range 1646–1202 cm −1 likely due to C–C and CC bond vibrations. In TiO 2 , the absorption band between 410–900 cm −1 is due to stretching vibrations of Ti–O–Ti bond.…”

Recent progress in TiO2–biochar-based photocatalysts for water contaminants treatment: strategies to improve photocatalytic performance

“…TiO 2 obtained by hydrolyzing tetrabutyl titanate is in situ grown onto biochar, followed by pyrolysis, a feasible synthetic path of TiO 2 –biochar composites. Luo et al 112 added tetrabutyl titanate into distilled water solution and introduced as-prepared biochar into the system. The solution was vigorously stirred to ensure that biochar was well distributed.…”

Synthesis and characterization of TiO2/hydrochar matrix composites for enhanced ammonia degradation

“…26,27 Biochar is mainly classied into pyrolytic carbon and hydrochar. The application of pyrolytic carbon as a photocatalytic carrier has been reported 28,29 Compositing TiO 2 with biochar has shown promise in designing photocatalysts with stable multiphase properties, improving catalyst aggregation, pore volume, and recycling efficiency. Biochar's unique ability to capture electrons transferred from TiO 2 enhances carrier separation efficiency.…”
