Embodiment 1
[0025] raw material:
[0026] Biochar material (white radish) is a commercially available raw material
[0027] Chloroplatinic acid hexahydrate is the raw material of Aladdin's official website
[0028] Cut the white radish into slices of 1*1*2cm, and soak it in 0.08mol / L chloroplatinic acid precursor solution for 6 hours.
[0029] After impregnation, the sample was freeze-dried at a freezing temperature of -60°C, a vacuum of 1 Pa, a freezing time of 1 day, and a drying time of 2 days to obtain a biochar precursor capable of maintaining the cell structure of the biochar material.
[0030] The biochar precursor was carbonized at a carbonization temperature of 600 °C, the heating rate was 2 °C / min, the holding time was 2 hours, and the protective atmosphere was Ar gas to obtain a Pt / C-N composite electrocatalytic material.
[0031] Using the bioporous carbon material loaded with Pt metal nanoparticles as the catalyst, its electrochemical hydrogen evolution performance was test...
