Nitrogen-rich metal-organic framework mediated Cu–N–C composite catalysts for the electrochemical reduction of CO2

Heterostructured MOFs photocatalysts for water splitting to produce hydrogen

“…Although many efforts have been made to improve the stability of MOFs such as introducing hydrophobic ligands, mixed metals, constructing interpenetrating structures, and postsynthetic modifications, the further development of new waterstable MOFs based photocatalyst is also full of challenges [97,98]. Recently, in order to overcome the poor conductivity and stability of most MOFs, a large number of studies have also explored MOFderived materials, which can be obtained by calcination MOFs in a certain atmosphere and converted them into metal compounds [99], carbon-containing materials [100], etc. These materials maintain the original pore structure of MOF and show good photocatalytic and electrocatalytic water activity.…”

Metal-Organic Frameworks as a Platform for CO2 Capture and Chemical Processes: Adsorption, Membrane Separation, Catalytic-Conversion, and Electrochemical Reduction of CO2

“…The results showed that the presence of Ag can increase the efficiency of CO greatly, hence inhibiting the H 2 production [190]. Cao, et al [191] used a nitrogen-rich Cu-BTT MOF as a catalyst for the electrochemical reduction of CO2. The results showed that the high-temperature pyrolysis product of Cu-N-C 1100 has the best catalytic activity for production of CO and HCOOH [191].…”

Sun, et al [192] synthesized nitrogen-doped mesoporous carbon nanoparticles that have atomically dispersed iron sites (namely mesoNC-Fe) using high-temperature pyrolysis of a Fe that contains ZIF-8 MOF.…”

A Highly‐Efficient Oxygen Evolution Electrocatalyst Derived from a Metal‐Organic Framework and Ketjenblack Carbon Material

“…However, the drawbacks of MOFs are (i) low electrical conductivity, [29] (ii) mass transport problem of reactants, products and electrolyte ions through their micropores, (iii) lack of stability especially in highly acidic or alkaline aqueous environments [30] . Therefore, electrocatalyst studies often use a MOF surface as a catalyst support or use the post‐synthetic calcination (pyrolysis) of MOFs at a high temperature to yield structured metal‐oxide materials [31–33] …”

“…[30] Therefore, electrocatalyst studies often use a MOF surface as a catalyst support or use the post-synthetic calcination (pyrolysis) of MOFs at a high temperature to yield structured metal-oxide materials. [31][32][33] In order to increase the electrical conductivity and structural stability, MOFs can be combined with more conductive materials such as graphene, [34] carbon nanotubes [35] or ketjenblack carbon (KB). [36] Among such carbon-based materials, ketjenblack has been used as an additive or a support in batteries and fuel cells since it has a high specific surface area of up to 1400 m 2 /g, excellent charge-transfer properties and high electrochemical stability.…”
