 Promotion effects of microwave and carbon dots interactions on hydrolysis for highly efficient hydrogen productionChunlin Luo, Shuai Liu, Yuxin Wang, Jianli Hu, Edward Lester and Tao Wu Energy, 2024, vol. 306, issue C Abstract: In this study, carbon dot-doped Co3O4 was synthesized and used in NaBH4 hydrolysis under both microwave and conventional heating. Microwave energy significantly increased the hydrogen generation rate with a CD-doped Co3O4 catalyst, ranging from 34.1 % at 35 °C to 70.7 % at 55 °C compared with conventional heating. This improvement is due to the combined contribution of microwave thermal and non-thermal effects. These phenomena greatly enhances the effective collision frequency of the reaction species at the interface of the catalyst. Furthermore, the kinetics of NaBH4 hydrolysis with the CD-doped Co3O4 catalyst follows a zero-order kinetic model. Under microwave irradiation, the HGR of the CD-doped Co3O4 catalyst was 4.5 times that of pure Co3O4 at 40 °C. Incorporating carbon dots (CDs) into the Co3O4 matrix simultaneously enhances microwave absorption, increases hydrophilicity, and reduces the activation energy needed for breaking down O–H bonds in H2O. These improvements are expected to boost the overall catalytic performance.
