“…16–24 In contrast, our catalytic system demonstrated the selective production of aromatic and aliphatic ring-reduced products through photocatalytic hydrogenolysis at room temperature, marking a pioneering achievement in the field. While previous reports for 4-O-5 cleavage relied on methods such as employing 4%Pt(P25)@TiO 2 under UV light and with the assistance of strong acid HCl (1.2 equivalents) for cleaving 4-O-5 linkages, 28 our study stands out as the first to achieve photocatalytic cleavage of this elusive linkage at room temperature without any additives, aligning perfectly with the principles of green chemistry. Furthermore, we demonstrated the photocatalytic valorization of a mixture of α-O-4, β-O-4, and 4-O-5 in producing liquid fuels, which is not reported under photocatalytic conditions.…”
