Plot of (a) H2 generation versus time; and (b) HGR of the hydrolysis of NaBH4 without retreatment of the CuNWs strips for two cycles, and (c) H2 generation versus time; and (d) HGR of NaBH4 with retreatment of the CuNWs using glacial acetic acid (GAA) in five consecutive cycles. (Conditions: CuNWs = 0.1 ng, 10 mL of [NaBH4] = 1 wt%, pH = 12, and temperature = 298 K).
