采用原位光还原法制备了高效可见光-近红外光催化剂Ag-RGO@{010} BiVO 4/RGO@{110} BiVO 4。RGO的横向电TE模式伴随着表面等离子体激元集体激发，迫使光催化剂吸收近红外光。可见光和近红外光照射下，15% Ag-RGO@{010} BiVO 4/RGO@{110} BiVO 4光催化剂在90 min内的降解率最高可达98.3%和66.1%，矿化率最高可达97.22%和74.25%。其优异的可见光和近红外光催化活性是由于等离子体银纳米粒子的横电TE模形成的局域电场和横磁TM模形成的局域磁场的共振效应可以加速载流子的分离，等离子体银纳米粒子的SPR效应诱导的高能载流子可以直接将有机污染物氧化成小分子。所合成的Ag-RGO@{010} BiVO 4/RGO@{110} BiVO 4复合光催化剂在可见光到近红外（NIR）波段具有优异的宽光谱响应，显示了其有效利用太阳能的潜力。
Highly efficient visible-NIR photocatalytic activity of Ag-RGO@{010}BiVO4/RGO@{110}BiVO4photocatalysts are successfully synthesized via an in situ photoreduction method. The transverse electric TE mode accompanied by surface plasmon collective excitations of RGO compel photocatalyst to absorb NIR light. Significantly, the degradation rate of 15%Ag-RGO@{010}BiVO4/RGO@{110}BiVO4photocatalysts can reach the highest 98.3% and 66.1%, and the mineralization yield can reach to 97.22% and 74.25% within 90 min under visible and 180 min NIR irradiation, respectively. The extraordinary visible and NIR photocatalytic activity is attributed to resonance effect of local electric field formed by transverse electric TE mode of RGO and local magnetic field formed by transverse magnetic TM of plasmonic Ag can accelerate carrier separation, and energetic carriers induce by SPR effect of plasmonic Ag nanoparticles can directly oxidize organic pollutants to small molecules. The as-synthesized Ag-RGO@{010}BiVO4/RGO@{110}BiVO4hybrid photocatalysts exhibit excellent wide-spectrum response to wavelengths ranging from visible to near-infrared (NIR), indicating its potential for effective utilization of solar energy.
