^aFresh borohydride solution (to get 25 mM) was injected into the reactor bottles at t = 0 h of all experiments, with exception of experiments 15 and 16.

^bFresh borohydride solution (to get 25 mM) was re-injected into the reactor bottles at t = 24.5 h. Total degradation after 31 h is also shown here.

^cFresh borohydride solution (to get 25 mM) was injected into the reactor bottles at t = 16 h. Total degradation after 24 h is also shown here.

^dPd = 0.5% w/w of Cu.

^eFresh borohydride solution (to get 25 mM) was re-injected into the reactor bottles at t = 13 h. Total degradation after 16 h is also shown here.

^fLoading dose of C-nCu⁰_W was 0.1 g L⁻¹.
