In the current scenario of climate change, the search for alternative energy sources is very important to reduce the use of fossil fuels. Undesired biomass (weed) from agricultural fields can be used to produce biofuels through nano catalysts enhanced gasification and process. Lignocellulosic part of weedy plants represents a potential alternative feedstock for economic production of bioethanol. Large numbers of weedy plant species are growing all over the world. However, high energy requirements and poor-quality biofuel products are the major constraints for utilization of this technology. Nanomaterials could be used as a catalyst to enhance the energy use efficiency and product quality. So, present study was conducted to produce bio-gas, bio-diesel and bio-char from mixed weed biomass of weeds like Carthamous oxyacantha, Asphodelus tenuifolius and Chenopodium album through gasification process using nano-materials as catalysts. Nickel and cobalt nano-particles were used as nano-catalysts to expedite the bio-chemical reactions for the generation of these products at lower temperatures i.e. (400 C°) in a muffle furnace. Further, these products were characterized using GC-MS analysis. It was observed that biodiesel contained 65.47% esters, which indicates its better quality than the normally produced biodiesel having 15–20% esters contents. Similarly, GC-MS analysis of biogas produced from mixed weed biomass showed 3.76% Methane, 8.32% Propane, 50.16% Ethene, 3.12% Propyne and 34.64% Methanol. The present results clearly exhibited the improved product quality and better energy use efficiency in gasification of weed biomass for bioenergy production.

在当前的气候变化情况下，寻找替代能源对于减少化石燃料的使用非常重要。来自农业领域的不良生物质（杂草）可用于通过纳米催化剂增强气化和工艺来生产生物燃料。杂草植物的木质纤维素部分代表了经济生产生物乙醇的潜在替代原料。全世界有大量杂草植物物种在生长。然而，高能量需求和劣质生物燃料产品是使用该技术的主要限制。纳米材料可以用作催化剂，以提高能源利用效率和产品质量。因此，进行了本研究，以从杂草等杂草生物质中产生沼气，生物柴油和生物炭。桐，Aphodelus tenuifolius和藜属专辑通过使用纳米材料作为催化剂的气化过程。镍和钴纳米颗粒被用作纳米催化剂，以加快生化反应，以便在马弗炉中在较低温度（400°C）下生成这些产物。此外，使用GC-MS分析对这些产品进行了表征。据观察，生物柴油中含有65.47％的酯，这表明其质量比正常生产的酯含量为15-20％的生物柴油要好。同样，从混合杂草生物质产生的沼气的GC-MS分析显示，甲烷为3.76％，丙烷为8.32％，乙烯为50.16％，丙炔为3.12％，甲醇为34.64％。目前的结果清楚地表明，在用于生物能源生产的杂草生物质气化中，产品质量得到了提高，能源利用效率更高。
