Here, we report a boron-doped copper catalyst on copper foam (B/CuxO/CF) that efficiently catalyzes FOR with an ultralow onset potential of 0.06 V at 100 mA cm?2. Compared to its phosphorus- and sulfur-doped counterparts (P/CuxO/CF and S/CuxO/CF), B/CuxO/CF exhibits markedly superior activity with ?97% formate yield. Surface analysis confirms the critical role of coexisting Cu+/Cu2+ species in B/CuxO in facilitating the key FOR steps of adsorption and CH cleavage, while the presence of boron improves charge transfer and active site availability. The limited HER activity of B/CuxO/CF was effectively addressed by coupling it with a Ni-based phospho-boride catalyst on Ni foam (NiPB/NF) that delivers selective and high hydrogen evolution performance, even in formaldehyde-containing media. The asymmetric NiPB/NF?B/CuxO/CF configuration achieved 100 mA cm?2 at only 0.25 V and sustained long-term stability with continuous HCHO replenishment, maintaining 300 mA cm?2 for over 8 hours. Operated in a membrane-free flow cell, the system maintained ?90% formate yield with a H2 production faradaic efficiency of ?190%, nearly doubling the hydrogen output. This hybrid strategy not only lowers energy input by 1.64 V compared to water electrolysis but also demonstrates viability for decentralized hydrogen and chemical co-production with economic benefits.
