Methane, as a low−carbon and clean energy source, plays a crucial role in ensuring energy security and advancing the realization of the "dual carbon" objectives. The direct catalytic conversion of methane to methanol under mild conditions has emerged as a key research focus in the field of energy catalysis. However, conventional single−metal catalysts often face challenges such as inefficient activation of the methane C—H bond and limited methanol yield. In this work, a Cu—Ru bimetallic modified H−ZSM−5 catalyst was synthesized via an ion exchange method. The influence of metal loading amount, loading sequence, and reaction parameters on catalytic performance was systematically evaluated. Results demonstrate that the co−loaded 1Cu/0.05Ru–ZSM−5 catalyst exhibits optimal activity, achieving a methanol yield of 38633.95 μmol·gcat−1·h−1 at 70 °C within 30 minutes using 0.75 mol·L−1 H2O2、3 MPa CH4, outperforming analogous single−metal catalysts. Characterization analyses reveal that Cu and Ru species are highly dispersed on the zeolite support, with electronic interactions between the two metals enhancing the adsorption and activation of methane molecules, thus contributing to improved catalytic efficiency. This research provides valuable theoretical perspectives for the rational design and development of bimetallic zeolite catalysts, which can facilitate efficient methane conversion under mild reaction conditions.

甲烷作为低碳清洁能源,其高效利用对保障能源安全、助力“双碳”目标实现意义重大。温和条件下甲烷直接转化制甲醇是能源催化领域的研究热点,然而,单金属催化剂存在对甲烷的 C—H键活化难、甲醇产率低等问题。通过离子交换法制备了CuRu双金属改性H−ZSM−5催化剂,系统探究了金属负载量、负载顺序,以及反应条件对甲烷制甲醇性能的影响。结果表明,同时负载的1Cu/0.05Ru−ZSM−5催化剂性能最优,在70℃、反应30 min、0.75 mol·L−1 H2O2、3 MPa CH4条件下甲醇收率可达38633.95 μmol·gcat−1·h−1,优于同类单金属催化剂。表征结果显示,Cu、Ru在载体上高度分散,通过电子协同作用增强了催化剂对甲烷分子的吸附与活化能力,从而提升了催化性能,为温和条件下甲烷高效转化的双金属沸石催化剂设计开发提供了理论支撑。
