Summary: Solar-driven photocatalytic hydrogenation of 5-hydroxymethylfurfural (HMF) to form 2,5-dihydroxymethylfuran (DHMF) was achieved using a PtNi-decorated TiO2 photocatalyst (PtNi/TiO2). PtNi/TiO2 exhibited excellent catalytic activity, achieving 100% HMF conversion efficiency and 99.7% DHMF selectivity under mild conditions. The strong electronic coupling between PtNi alloy and TiO2, as well as the enhanced aldehyde adsorption configuration, played important roles in the photocatalytic process.

Summary: The solvent effect on the selective production of furfural or 5-hydroxymethylfurfural (HMF) from fructose was investigated using experiments, nuclear magnetic resonance (NMR), and molecular dynamics (MD) simulation. It was found that solvent polarity and basicity played a crucial role in the selective formation of furfural and HMF. The arrangement of solvents around fructose tautomers, particularly around different C-OH, resulted in different products. High yields of furfural (76.2%) and HMF (90.5%) were achieved in γ-butyrolactone (GBL)-H2O and dimethyl sulfoxide (DMSO)-H2O solvents.

Summary: This study focuses on the catalytic conversion of the biobased chemical 5-hydroxymethylfurfural (HMF) into high-value-added products. By optimizing the metal and reduction temperature, Ni1.5Al-LDO-700 and Ni1.5GaAl-LDO-700 catalysts achieved yields of >99% and 95.6% for bihydroxymethyltetrahydrofuran (BHMTHF) and bihydroxymethylfurfural (BHMF), respectively. Doped Ga disrupted the Ni arrangement, weakened furan ring adsorption, and selectively produced BHMF by inhibiting deep hydrogenation.

Summary: In this study, an alloying method was used to introduce Fe species into Ni-Al catalysts to form oxyphilic FeNi alloy, allowing for the selective conversion of HMF to DMF. The results showed that the Ni-Fe-Al alloy reduced the hydrogen adsorption and activation capability, leading to the formation of DHMF and 5-MFA instead of DMF during the hydrogenation of HMF. The FeNi alloy exhibited high affinity for the adsorption and activation of C-OH in DHMF and 5-MFA, promoting their hydrogenolysis to DMF.

Summary: A PtNi/HT catalyst was prepared and used for glucose hydrogenation, achieving a high conversion rate of 95.7% and selectivity of 90.1% to polyols at 393 K in water. The catalyst demonstrated stability and recyclability for glucose conversion. Lower reaction temperatures favored hexitol production, while higher temperatures facilitated the generation of polyols with less carbon. The Pt delta--Ni delta+ pair on PtNi/HT played a crucial role in H2 activation and adsorption during glucose hydrogenation. The basic support of PtNi/HT efficiently catalyzed glucose isomerization and retro-aldol reaction in the aqueous phase.
