“…However, larger driving pressure gave rise to reduction of the loading strength of catalyst, so the catalyst loaded on the copper foam easily fell off from copper foam. 41 Thus, with 0.102 MPa driving pressure, the maximum amount of catalyst loaded on copper foam was obtained in the tested range of driving pressure.…”

In order to realize uniformly loading catalyst on copper foam, a new device was designed to drive catalyst precursor solution to flow into the inner pore structures of copper foam by changing driving pressure and flow rate. The three-dimensional models of copper foam loaded with catalyst using different impregnation methods were reconstructed by Micro-CT. The catalyst loading distribution was studied by Micro-CT and SEM. Moreover, methanol steam reforming reaction performance of microreactor with copper foam loaded with catalyst using different methods was compared and analyzed. The results showed that the best loading performance of copper foam was obtained when driving pressure and flow rate of catalyst precursor solution were 0.102 MPa and 0.3 L/min, respectively. Compared with traditional impregnation method, copper foam using active impregnation method exhibited more uniform distribution of catalyst and better reaction performance for hydrogen production. This work provides a feasible method to optimize catalyst loading process.

“…Another way to replace the carbon black and reduction of Pt consumption is to apply carbon nanotubes (CNT) to the catalyst formation. CNT has the properties of excellent corrosion resistance, electronic conductivity and specific surface area [ 45 , 46 ], and can prevent the aggregation of platinum, resulting in enhancement of catalytic activity [ 4 , 47 ]. Also, long-term durability mentioned by the demerit of CB was crucial point to overcome for the commercialization of fuel cell.…”

Developments of high efficient materials for electrocatalyst are significant topics of numerous researches since a few decades. Recent global interests related with energy conversion and storage lead to the expansion of efforts to find cost-effective catalysts that can substitute conventional catalytic materials. Especially, in the field of fuel cell, novel materials for oxygen reduction reaction (ORR) have been noticed to overcome disadvantages of conventional platinum-based catalysts. Various approaching methods have been attempted to achieve low cost and high electrochemical activity comparable with Pt-based catalysts, including reducing Pt consumption by the formation of hybrid materials, Pt-based alloys, and not-Pt metal or carbon based materials. To enhance catalytic performance and stability, numerous methods such as structural modifications and complex formations with other functional materials are proposed, and they are basically based on well-defined and well-ordered catalytic active sites by exquisite control at nanoscale. In this review, we highlight the development of nano-structured catalytic materials for ORR based on recent findings, and discuss about an outlook for the direction of future researches.
