A novel TiO2(B) confined in porous bio-derived carbon has been prepared for dehydrogenated catalyzation of NH3BH3. The microstructural characterizations of as-prepared samples show that the nanoconfinement in well-organized micro/mesopores of carbon can avoid the aggregations of TiO2(B) nanoparticles and NH3BH3. The dehydrogenation measurement demonstrates the dehydrogenated thermodynamic and dynamic properties of NH3BH3 could be improved under the con-catalyzation of TiO2(B) and porous carbon. The results suggest that both TiO2(B) and porous bio-derived C are promising catalysts. Additionally, it also provides a high-value solution for the disposal of agricultural wastes.
