      Pure t-LaVO4£¨Ë®ÈÈ·¨ºÏ³É£© was prepared through several steps using a hydrothermal method. First, a predetermined amount of La2O3 was dissolved in 6 M HNO3 solution. Then, the obtained La(NO3)3 solution was mixed with 0.4 M NH4VO3 at the V:La mole ratio of 1:1 to form a precipitate, followed by adjusting the pH of the new mixture to 7 with a 2 M NH3 solution and transferring it into a 100-mL Teflon-lined stainless-steel autoclave. The autoclave was sealed and maintained at 180¡ãC for 24 h and then air-cooled to room temperature. The resulting products were filtered, washed with deionized water, and dried at 80¡ãC for 12 h.
        Pure m-LaVO4£¨ÆÕͨ³Áµí·¨£© was prepared via a precipitation method. Specifically, 20 mL of0.4 M NH4VO3 and 20 mL of 0.4 M La(NO3)3 were used for the mixing and generation of a precipitate. The pH of the mixture was controlled at 5, using a 2 M NH3 solution. After aged at room temperature for 30 min, the precipitate was filtered, washed three times by deionized water, dried at 100 ¡æ for 12 h and calcined at 600 ¡ãC for 4 h.The LaVO4/g-C3N4 composite catalysts were prepared as follows. LaVO4 and g-C3N4 with given ratios were mixed and ground in an agate mortar for 20 min, and then calcined at 450¡æ for 2 h to obtain the LaVO4/g-C3N4 catalyst. The actual LaVO4 concentration was determined with thermogravimetry(TG) experiments (see Figure S1 in the Supporting Information). For simplification, the synthesized LaVO4/gC3N4 composites are denoted as xwt %t-LC or xwt %m-LC,in which xrepresents the LaVO4 concentration.
