1 Introduction Photocatalysis can convert solar energy into chemical energy, such as through photocatalytic water splitting to produce hydrogen [1, 2], photocatalytic reduction of CO2 [3, 4], and photocatalytic degradation of organic pollutants [5, 6] and reduction of heavy metal ions [7, 8]. In addition, photocatalysis has significant advantages in chemical synthesis [9, 10].
