Visible-light-enhanced hydrogen evolution from catalytic hydrolysis of ammonia borane using Ru nanoparticles supported on CdS-modified graphitic carbon nitride

“…2(a and b), it is clear that g-C 3 N 4 presents the feature of nanosheet structure, and diffraction peaks centered at 13.21 and 27.31 can be indexed to (100) and (002) planes, respectively, which are well consistent with literature results. [14][15][16][18][19][20] As can be seen from Fig. 2(c and d), compared with pristine g-C 3 N 4 , the morphology and phase composition of 10-CdS/C 3 N 4 are distinctly changed.…”

“…Therefore, it can be concluded that the Ru NPs act as electron acceptors and greatly boost the separation of e À /h + pairs from the photoexcited CdS/C 3 N 4 . [9][10][11][12][13][14][15][16] Catalytic activity of Ru/CdS/C 3 N 4…”

“…Similar regularity has been reported by plenty of studies. 16,20,24,26,27 To investigate the effect of catalyst dosage on hydrolytic dehydrogenation, the AB concentration was fixed at 0.20 mol L À1 , and the catalyst dosage varied from 15 to 30 mg. As shown in Fig. 5(b), increasing the catalyst dosage can remarkably promote hydrogen evolution from AB hydrolysis.…”

“…All these findings are well consistent with literature results. 16,20,24,26,27 Visible-light-enhanced hydrogen evolution As demonstrated by many studies, due to the light irradiation, AB hydrolysis over Schottky photocatalysts can be greatly enhanced, and how to strengthen the light harvest and conversion is of key importance for further boosting the photocatalytic hydrolysis of AB to generate hydrogen. To this end, the proposed strategy here is to modify raw g-C 3 N 4 with CdS, constructing type-II heterojunction with a wider light adsorption region and lower recombination rate of photoexcited charge carriers.…”

“…To further enhance the dehydrogenation of AB, photocatalytic hydrolysis has been rapidly developed recently, and a wide range of Schottky photocatalysts composed of metal-based catalysts and semiconductors have been reported such as M/ NH 2 -MIL-101 (M = Cu, Co, and Ni), 9 CoNi/TiO 2 , 10 Pd/H 2 Ti 3 O 7 , 11 Ru/MoS 2 , 12 PtRu/b-SiC, 13 CuCo/C 3 N 4 , 14 Ni/C 3 N 4 , 15 and RuP 2 / C 3 N 4 . 16 For the construction of a photocatalyst, the selection of an appropriate semiconductor is of key importance. Graphitic carbon nitride (g-C 3 N 4 ), a polymeric and metal-free semiconductor, presents many merits including low cost, good chemical stability, a relatively narrow bandgap (ca.…”
