Formic acid (FA) has tremendous potential as a safe and convenient source of hydrogen for renewable energy storage, but controlled and efficient dehydrogenation of FA by a robust solid catalyst constitutes a major challenge. In this report, a metal nanoparticle functionalized zeolitic imidazolate framework (ZIF) derived N-decorated nanoporous carbon (NPC) support was fabricated and used as an efficient FA decomposition catalyst for the first time. The resultant AgPd@NPC catalyst exhibited 100% H2 selectivity and high catalytic activity (TOF = 936 h−1) toward the dehydrogenation of formic acid at 353 K. The synergetic interaction between the metal nanoparticles and NPC greatly enhances the catalytic performance of the as-prepared catalyst.

Levulinic acid (LA) is a versatile key building block in the conversion of carbohydrates and it is an important basic chemical with various potential uses. MIL-100(Fe) loading with insoluble lysine functionalized phosphotungstic acid (Lys-PM 2 ) as heterogeneous catalysts have been synthesized for the conversion of glucose to LA in water. The optimized yield of LA is obtained by using Lys-PM 2 to catalyze glucose conversion is comparable to the majority of effective catalysts. The highest yield of LA (57.9%) is obtained at 150 °C for 9 h with 100 mg glucose and 25 mg Lys-PM 2 , since the Brønsted acidity and Lewis acidity of Lys-PM 2 . And the catalyst is able to recycle at least four times. It demonstrates the potential of Lys-PM 2 for the conversion of biomass.
