Activated carbon (AC) and glass fiber (GF) were functionalized with gold nanoparticles to test the efficiency of low cost supports and its effect on catalytic activity. The resulting supported gold was characterized using Transmission Electron Microscopy (TEM), Scanning Electron Microscopy (SEM), and Energy Dispersive X-Ray Spectroscopy (EDS). The analysis shows the nanoparticle size to be 15 nm and confirms its presence on the supports. The catalytic activity analysis showed the generation of hydrogen gas was increased when using a support and showing the greatest improvement with the AC Au having a rate constant of 404.5 mM −1 min −1 , compared to the glass fiber and unsupported nanoparticles which produced hydrogen at rates of 154.5 mM −1 min −1 and 0.700 mM −1 min −1 respectively. The catalytic activity was also examined at varied pH of 6, 7, and 8, as well as varied temperature of 273, 296, and 308 K, showing the mo...

低成本的金载体上支持的金纳米颗粒，用于从氢气原料中生成氢气

用金纳米粒子对活性炭（AC）和玻璃纤维（GF）进行功能化，以测试低成本载体的效率及其对催化活性的影响。使用透射电子显微镜（TEM），扫描电子显微镜（SEM）和能量色散X射线光谱（EDS）对得到的负载金进行表征。分析显示纳米颗粒大小为15 nm，并确认其在载体上的存在。催化活性分析表明，与玻璃纤维和无载体纳米粒子相比，当使用载体时，氢气的生成量增加，并且使用速率为404.5 mM -1 min -1的AC Au时，其最大的改进是最大的改善。速率分别为154.5 mM -1 min -1和0.700 mM -1 min -1。还在6、7的不同pH下检查了催化活性
