摘要：Uniform NaTaO_3 ca. 15 nm and ca. 70 nm nanocrystals were synthesized via a novel surfactant-free solvothermal reaction. The acidic alkoxide hydrolyzation leads to small size and high surface area particles. The different size of the nanocrystals was controlled by altering concentration. The alkoxide-based synthetic route leads to small particle size and high surface area, which improved the charge separation and migration of photo-generated carriers and benefited the surface chemical reaction of catalysts. As a result, the high total yield of photocatalytic water splitting hydrogen generation was obtained, which was as high as 3.106 mmol h~(-1) g~(-1).
