[0042] A two-dimensional flexible CuBDC@Ti 3 C 2 T x Electrode Fabrication Method Seamlessly Coating CuBDC on Electronegative Ti 3 C 2 T x Fabrication of 2D flexible CuBDC@Ti on nanosheets 3 C 2 T x electrode, the specific steps are as follows:
[0043] (1) 1-30g of 1,4-phthalic acid (H 2 BDC) mixed in 100-1000mL of DMF and 50-500mL of CH 3 CN as the bottom layer.
[0044] (2) On this solution, 50-500mL of DMF and 50-500mL of CH 3 CN is added slowly and carefully as an intermediate or spacer layer.
[0045] (3) Finally, in 50-500mL of DMF and 100-1000mL of CH 3 Add 1-10 g of Ti to CN mixture 3 C 2 T x Nanosheets and 3-30g Cu(NO 3 ) 2 ·3H 2 O, slowly add to the tube as the top layer. The solution in the tube was left undisturbed at room temperature for 24 hours to allow the reaction to occur.
Embodiment 1
[0048] 1. Two-dimensional flexible CuBDC@Ti 3 C 2 T x The specific steps for electrode preparation are as follows:
[0049] 10g of 1,4-phthalic acid (H 2 BDC) mixed in 200 mL of DMF and 100 mL of CH 3 CN as the bottom layer.
[0050] On this solution, 100mL of DMF and 100mL of CH 3 CN is added slowly and carefully as an intermediate or spacer layer.
[0051] Finally, in 100mL of DMF and 200mL of CH 3 Add 5 g of Ti to the CN mixture 3 C 2 T x Nanosheets and 10g Cu(NO 3 ) 2 ·3H 2 O, slowly add to the tube as the top layer. The solution in the tube was left undisturbed at room temperature for 24 hours to allow the reaction to occur.
[0052] 2. The obtained 2D flexible CuBDC@Ti 3 C 2 T x Electrodes for ENRA
[0053] 2D Flexible CuBDC@Ti 3 C 2 T x The electrode can be directly used as a working electrode, with platinum electrode as counter electrode and Ag / AgCl electrode as reference electrode to form a three-electrode system; the three-electrode system is pla...
Embodiment 2
[0059] 2D Flexible CuBDC@Ti 3 C 2 T x The preparation of electrodes and the method for catalytic reduction of nitrate are as in Example 1, except that CuBDC@Ti is prepared 3 C 2 T x without adding Ti 3 C 2 T x Nanosheets.
[0060] from Figure 4 It can be seen that the obtained CuBDC electrode still maintains the nanosheet structure with thicker thickness, possibly with partial stacking.
