“…91 This causes the HER to proceed in an uphill reaction pathway with a Δ G ° > 0, while the PDR, on the other hand, proceeds downhill with Δ G ° < 0. 92 Driving a DFP system can pose certain challenges due to (i) the band alignments between the CB and VB of the MOF SC. This means that to have an efficient DFP, one must carefully consider the position of the CB and VB during the engineering of the MOF SC, more favorably, a type II heterojunction will be much suited for this purpose.…”
