Photoreforming has emerged as a novel technology expected to obtain chemical energy through solar energy transformation. In this way, sustainable valorization of glycerol, a biodiesel by-product, to clean fuels is a promising alternative to help meet the world's growing energy demand. In this work, TiO₂/rGO(x)/Pt(y) photocatalysts have been developed for hydrogen production from synthetic and crude glycerol solutions. The effect of several key operating parameters (including vol% of glycerol, pH, catalyst loading, wt% of GO, wt% of Pt, temperature, and light source) on hydrogen production rate has been studied. The results indicated different optimal operating parameters depending on glycerol origin, achieving up to 70.8 and 12.7 mmol h⁻¹ g⁻¹ of hydrogen using synthetic glycerol and crude glycerol, respectively. Additionally, GO nanosheets and Pt nanoparticles strongly influenced the hydrogen production rate but not the overall reaction mechanism. Impurities contented in crude glycerol are key factors in developing realistic hydrogen production processes.

光重整已成为一种有望通过太阳能转化获得化学能的新技术。这样，生物柴油副产品甘油的可持续增值以清洁燃料是一种有希望的替代方案，可以帮助满足世界不断增长的能源需求。在这项工作中，已经开发了TiO ₂ / rGO（x）/ Pt（y）光催化剂，用于从合成和粗制甘油溶液中制氢。研究了几个关键操作参数（包括甘油的体积百分比，pH，催化剂负载量，GO的重量％，Pt的重量％，温度和光源）对制氢速率的影响。结果表明，不同的最佳操作参数取决于甘油的来源，达到了70.8和12.7 mmol h ^-1  g ^-1分别使用合成甘油和粗甘油制氢 此外，GO纳米片和Pt纳米粒子强烈影响制氢速率，但不影响整体反应机理。粗甘油中的杂质是发展现实的制氢工艺的关键因素。
