Formic acid (HCOOH), with a hydrogen capacity of 4.3 wt. %, has attracted increasing interest in the utilization as a promising H 2 carrier. The CO 2 -HCOOH cycle is believed to be a simple and environmental-friendly process for the charge and discharge of H 2 . In this review, we summarize the state-of-the-art technologies and recent results of the heterogeneously catalyzed dehydrogenation of formic acid. Based on these achievements, future outlooks for improving this system for practical applications are proposed.

“…Very recently, our group developed Pt 1 /Te single-atom catalysts, which delivered the TOF of 1206 h −1 with 100% selectivity for H 2 at 25°C via a plasmon-enhanced catalytic process 14 . In spite of these advances, the expensive cost of noble-metal-based catalysts impels people to exploit nonnoble-metal-based catalysts for HCOOH decomposition, which has achieved exciting advances recently, especially for homogeneous catalysts [15][16][17][18][19][20][21][22][23][24] . For example, Beller et al 17 reported that a Fe catalyst with an extra equivalent of tetradentate auxiliary ligand decomposed HCOOH at 80°C with the TOF of 9425 h −1 .…”

As a promising hydrogen carrier, formic acid (HCOOH) is renewable, safe and nontoxic. Although noble-metal-based catalysts have exhibited excellent activity in HCOOH dehydrogenation, developing non-noble-metal heterogeneous catalysts with high efficiency remains a great challenge. Here, we modulate oxygen coverage on the surface of Ti 3 C 2 T x MXenes to boost the catalytic activity toward HCOOH dehydrogenation. Impressively, Ti 3 C 2 T x MXenes after treating with air at 250°C (Ti 3 C 2 T x-250) significantly increase the amount of surface oxygen atoms without the change of crystalline structure, exhibiting a mass activity of 365 mmol•g −1 •h −1 with 100% of selectivity for H 2 at 80°C, which is 2.2 and 2.0 times that of commercial Pd/C and Pt/C, respectively. Further mechanistic studies demonstrate that HCOO* is the intermediate in HCOOH dehydrogenation over Ti 3 C 2 T x MXenes with different coverages of surface oxygen atoms. Increasing the oxygen coverage on the surface of Ti 3 C 2 T x MXenes not only promotes the conversion from HCOO* to CO 2 * by lowering the energy barrier, but also weakens the adsorption energy of CO 2 and H 2 , thus accelerating the dehydrogenation of HCOOH.
