Along with the great efforts in producing clean and low-cost fuel and chemicals, in this work, novel nanocatalysts are reported for the fast pyrolysis of the bagasse. To this end, different catalyst supports were employed to load Mo oxides or sulfides through incipient wetness impregnation. The prepared nanocatalysts were characterized by X-ray diffraction to determine the formed phases, N₂ adsorption/desorption to clarify the surface properties, and SEM to observe the morphology and energy-dispersive X-ray to provide the atomic mapping. A series of nanocatalysts including the Mo sulfide loaded over graphene oxide (MoS₂/GrO) or porous graphene (MoS₂/graphene), Mo oxide loaded over charcoal, and Co-Mo oxide loaded over MgO were studied in the fast pyrolysis of the bagasse. The results revealed that the use of catalyst decreased the bio-oil yield of the process. Interestingly, it was found the fast pyrolysis of the bagasse is dependent on the used catalysts and the fractions of bio-oil can be determined according the catalysts types. It was found that with accordance to the demanded chemicals, the catalysts can be chosen which is highly valuable in producing chemicals and each catalysts support results in a specific set of products. In general, the acetic acid was the main product without using catalyst, and by using the MoS₂/GrO nanocatalyst, the phenols were formed dominantly which are of great importance in different industries. This novel work successfully revealed that the metal-based catalysts can be employed instead of the zeolites which paves the way toward using low-cost metallic catalysts in producing bio-chemicals and bio-oils.

随着生产清洁和低成本燃料和化学品的巨大努力，在这项工作中，据报道，新型纳米催化剂可用于蔗渣的快速热解。为此，采用了不同的催化剂载体，通过初期湿润浸渍来负载Mo氧化物或硫化物。制备的纳米催化剂通过X射线衍射表征，确定形成的相，N ₂吸附/解吸，以澄清表面性质，并且SEM观察形态和能量分散X射线，以提供原子图。一系列纳米催化剂，包括负载在氧化石墨烯（MoS ₂ / GrO）上的硫化钼或多孔石墨烯（MoS ₂/石墨烯），木炭上负载的Mo氧化物和MgO上负载的Co-Mo氧化物在蔗渣的快速热解中进行了研究。结果表明，催化剂的使用降低了该方法的生物油产率。有趣的是，发现蔗渣的快速热解取决于所用的催化剂，并且可以根据催化剂的类型确定生物油的馏分。已经发现，根据所需的化学品，可以选择在生产化学品中非常有价值的催化剂，并且每种催化剂都可以得到一组特定的产物。通常，乙酸是不使用催化剂而使用MoS ₂的主要产物。在/ GrO纳米催化剂中，酚类占主导地位，这在不同行业中具有重要意义。这项新颖的工作成功地揭示了可以使用金属基催化剂代替沸石，这为使用低成本金属催化剂生产生物化学品和生物油铺平了道路。
