Enhanced dehydrogenation performance of ammonia borane con-catalyzed by novel TiO2(B) nanoparticles and bio-derived carbon with well-organized pores.

A novel TiO 2 (B) confined in porous bio-derived carbon has been prepared for dehydrogenated catalyzation of NH 3 BH 3. The microstructural characterizations of as-prepared samples show that the nanoconfinement in well-organized micro/mesopores of carbon can avoid the aggregations of TiO 2 (B) nanoparticles and NH 3 BH 3. The dehydrogenation measurement demonstrates the dehydrogenated thermodynamic and dynamic properties of NH 3 BH 3 could be improved under the con-catalyzation of TiO 2 (B) and porous carbon. The results suggest that both TiO 2 (B) and porous bio-derived C are promising catalysts. Additionally, it also provides a high-value solution for the disposal of agricultural wastes. • Bio-derived C with well-organized micro/mesopores in walls of its microchannel. • A novel TiO 2 (B) nanoconfined into pores of bio-derived C. • Enhanced dehydrogenation of NH 3 BH 3 with individual or complex of C and TiO 2 (B). • Best dehydrogenation behavior of C-TiO 2 (B)/NH 3 BH 3 than C/NH 3 BH 3 and TiO 2 (B)/NH 3 BH 3.
