磷掺杂氮化碳管的制备及其光催化制氢性能OA
Synthesis of Phosphorus-doped Carbon Nitride Nanotubes and Their Photocatalytic Hydrogen Evolution Performance
联合水热法和热聚合法成功制备氮化碳管并对其进行磷掺杂改性.测试结果表明:磷掺杂显著增强氮化碳管(PTCN)对可见光的吸收能力,提高了太阳能的利用率;同时磷的掺杂也促进了氮化碳管光生载流子的迁移和分离.磷掺杂氮化碳管具有优异的光催化制氢活性,产氢速率可达3 352.3 μmol·h-1·g-1,分别为未掺杂磷的氮化碳管(TCN)和块状氮化碳(BCN)的2.4倍和11.6倍.
Nitrogen-carbon tubes were successfully synthesized via a combined hydrothermal and ther-mal polymerization method,followed by phosphorus doping modification.The test results indicate that phosphorus-doped nitrogen-carbon nanotubes exhibit significantly enhanced visible light absorption ca-pacity,thereby improving solar energy utilization efficiency.Simultaneously,phosphorus doping facili-tates the migration and separation of photogenerated charge carriers in the nitrogen-carbon nanotubes.The phosphorus-doped nitrogen-carbon nanotubes demonstrate excellent photocatalytic hydrogen evo-lution activity,with a hydrogen production rate reaching 3 352.3 μmol·h-1·g-1,which is approxi-mately 2.4 times and 11.6 times higher than that of undoped phosphorus nitrogen-carbon nanotubes and bulk carbon nitride,respectively.
