Embodiment 1
[0029] A CQDs / Bi 2 MoO 6 Composite photocatalyst consisting of 50-100nm nanosheet Bi 2 MoO 6 and 5-10nm carbon quantum dots, and the CQDs nanoparticles are distributed in the nanometer-sized sheet-like Bi 2 MoO 6 Above, calculated by mass percentage, CQDs of nanoparticles: nanometer-sized sheet-like Bi 2 MoO 6 3.2%: 96.8%.
[0030] One of the above CQDs / Bi 2 MoO 6 Composite photocatalyst preparation method specifically comprises the following steps:
[0031] (1), the Bi(NO 3 ) 3 ·5H 2 O is dissolved in nitric acid to obtain Bi(NO 3 ) 3 solution;
[0032] Na 2 MoO4 2H 2 O was dissolved in deionized water to obtain Na at a concentration of 0.05 mol / L 2 MoO 4 solution;
[0033] Then calculated by molar ratio, that is, Bi(NO 3 ) 3 Bi in solution 3+ : Na 2 MoO 4 MoO in solution 4 2- For a ratio of 2:1, the Bi(NO 3 ) 3 solution and Na 2 MoO 4 The solution was mixed evenly to obtain a light yellow suspension;
[0034] (2) Add the CQDs aqueous solution t...
Embodiment 2
[0042] The difference between this embodiment and embodiment 1 is only: CQDs and Bi 2 MoO 6 The mass ratio is 1%: 99%, and all the other contents are identical with those described in Example 1. Known through detection and analysis: the CQDs / Bi obtained by the present embodiment 2 MoO 6 The degradation rate of rhodamine B of the composite photocatalytic material under the same conditions as the composite material obtained in Example 1 was 80.7%.
Embodiment 3
[0044] The difference between this embodiment and embodiment 1 is only: CQDs and Bi 2 MoO 6 The mass ratio is 6%: 94%, and all the other contents are identical with those described in Example 1. Known through detection and analysis: the CQDs / Bi obtained by the present embodiment 2 MoO 6 The degradation rate of rhodamine B of the composite photocatalytic material under the same conditions as the composite material obtained in Example 1 was 76.8%.
