Embodiment 1
[0037] A wood-based porous activated carbon / Ni 0.2 Mo 0.8 N electrocatalytic material and its preparation method. The steps of the preparation method described in this embodiment are:
[0038] Step 1. Cut the wood into pieces, wash them twice with deionized water, and dry them at 55°C to obtain the pretreated wood pieces; impregnate 1 mass part of the pretreated wood blocks into 5 mass parts of 15wt% ZnCl 2 Solution, under the condition of 105 ℃ for 45 hours, promptly get the wood block treated with zinc chloride; the wood block treated with zinc chloride is heat treated in high-purity argon atmosphere and 800 ℃ for 2 hours, and then use Washing with deionized water three times and drying to obtain a wood-based porous activated carbon material.
[0039] Step 2, the Na of 1 mass part 2 MoO 4 2H 2 O and 1 mass part of NiCl 2 ·6H 2 O was added to 98 parts by mass of deionized water, and stirred for 10 minutes to obtain a mixed solution; the mixed solution was added to a ...
Embodiment 2
[0043] A wood-based porous activated carbon / Ni 0.2 Mo 0.8 N electrocatalytic material and its preparation method. It is characterized in that the steps of the preparation method are:
[0044] Step 1. Cut the wood into pieces, wash them three times with deionized water, and dry them at 60°C to obtain the pretreated wood pieces; immerse 1 mass part of the pretreated wood blocks in 4 mass parts of 20wt% ZnCl 2 solution, treated at 110°C for 48 hours to obtain a wood block treated with zinc chloride; the wood block treated with zinc chloride was heat-treated for 3 hours in a high-purity argon atmosphere and at 850°C, and then used Washing with deionized water three times and drying to obtain a wood-based porous activated carbon material.
[0045] Step 2, the Na of 1 mass part 2 MoO 4 2H 2 O and 1.5 parts by mass of NiCl 2 ·6H 2 O was added to 97.5 parts by mass of deionized water and stirred for 15 minutes to obtain a mixed solution; the mixed solution was added to a hydr...
Embodiment 3
[0049] A wood-based porous activated carbon / Ni 0.2 Mo 0.8 N electrocatalytic material and its preparation method. It is characterized in that the steps of the preparation method are:
[0050] Step 1. Cut the wood into pieces, wash twice with deionized water, and dry at 65°C to obtain the pretreated wood pieces; impregnate 1 mass part of the pretreated wood blocks into 3 mass parts of 30wt% ZnCl 2 solution, treated at 115°C for 50 hours to obtain a wood block treated with zinc chloride; heat-treating the wood block treated with zinc chloride in a high-purity argon atmosphere at 900°C for 4 hours, and then use Washing with deionized water for 4 times and drying to obtain a wood-based porous activated carbon material.
[0051] Step 2, the Na of 1 mass part 2 MoO 4 2H 2 O and 2 parts by mass of NiCl 2 ·6H 2 O was added to 97 parts by mass of deionized water, and stirred for 20 minutes to obtain a mixed solution; the mixed solution was added to a hydrothermal reaction kett...
