• N self-doped 3D macroporous pollen-like carbon (pollen-C) derived from the biomass of rape pollen shows excellent performance in the selective hydrogenation of 1, 3-butadiene after loading Pd. • The content and type of N self-doping on pollen-C affect the particle size and the valence of the supported Pd. • Large-sized Pd (112.6 nm) can still have good activity (98.5%) in the selective hydrogenation of 1, 3-butadiene. The selective hydrogenation of 1, 3-butadiene values in industrial application and scientific research, and Pd catalysts are widely used in this reaction. However, it is still a challenge to achieve high butenes selectivity at a high conversion rate. Here we report the N self-doped 3D macroporous pollen-like carbon (pollen-C) derived from the biomass of rape pollen to achieve higher butenes selectivity at high conversion rates after Pd loading. Experimental results reveal that the properties of pollen-C, especially the content and type of N doping, will influence the particle size and the valence of the supported Pd, thereby affecting the catalytic performance. As a result of more N dopant and unique macroporous structure, the Pd/pollen-C-500 showed better butenes selectivity of 95% at 80 °C than Pd/commercial activated carbon (Pd/AC). [Display omitted] For Table of Contents Use Only The N self-doped macroporous pollen-C was achieved by a facile method, which improved the butenes selectivity in hydrogenation of 1, 3-butadiene.
