%X BiVO<sub>4</sub>作为一种优良的半导体材料，在光催化领域内引起了人们广泛的关注。与其他半导体材料相比，单相晶相BiVO<sub>4</sub>有着更低的带隙能(约2.4 eV)，因此在可见光区的响应特性，赋予了其优越的光催化性能。本论文综述了BiVO<sub>4</sub>微纳米材料的常见液相合成法，包括水热法、共沉淀法、溶胶–凝胶法、微乳液法等。针对单一BiVO<sub>4</sub>光生电子和空穴易复合、迁移速率较慢等缺点，本文归纳了几种改性方法：形貌调控，调节其形状及比表面积大小，实现BiVO<sub>4</sub>的光催化能力的提高；构建异质结，与半导体材料、贵金属等复合，改变其表面组成，从而提高BiVO<sub>4</sub>的光催化性能。最后分析了目前的制备方法中的不足之处并提出展望。<br />
As an excellent semiconductor material, BiVO<sub>4</sub> has attracted wide-spread attention in the field of photocatalysis. In comparison with other common semiconductor materials, the monoclinic has a lower band gap energy (about 2.4 eV) and thereby exhibiting visible light responsive and excellent photocatalytic properties. In this work, we will overview the common liquid-phase synthetic methods of BiVO<sub>4</sub> micro/nanomaterials, including the hydro-thermal method, co-precipitation method, sol-gel method, and microemulsion method. In addition, in view of the shortcomings of easy recombination of photogenerated electrons and holes, and slow migration rate, several modification methods for prime BiVO<sub>4</sub> are introduced. Mor-phology control: adjust its shape and specific surface area to achieve the enhancement of photo-catalytic/adsorption capacity of BiVO<sub>4</sub>. Construction of heterojunction: compound with semiconductor materials, and noble metals to change its surface composition to improve the pho-tocatalytic performance of BiVO<sub>4</sub>. Finally, the drawbacks of the current preparation methods are analyzed and prospects are proposed.
