“…The interplanar crystal spacings of 0.34 and 0.288 nm are regarded as (110) and (301) crystal faces, respectively, which are consistent with the XRD results. 16,22 EDS mapping analysis in Figure S4 revealed that C, N, O, and V elements were uniformly distributed on the catalyst. Therefore, the results of SEM, TEM, HRTEM, and EDS mapping strongly prove that the uniform loading of V 2 O 5 on the carrier 3D g-C 3 N 4 can be realized by using vanadium-based ionic liquid [(C 8 H 17 ) 3 NCH 3 ] 3 H 3 V 10 O 28 as the vanadium source and template agent.…”
