TL;DR: More than 100 articles related to anode catalysts for the direct methanol fuel cell (DMFC) are reviewed, mainly focusing on the three most active areas: (1) progress in preparation methods of Pt-Ru catalysts with respect to activity improvement and utilization optimization; (2) preparation of novel carbon materials as catalyst supports to create a highly dispersed and stably supported catalysts; (3) exploration of new catalysts having a low noble metal content and non-noble metal elements through fast activity down-selection methods such as combinatorial methods.

TL;DR: In this article, the authors reviewed over 100 articles related to heat-treated Fe-and Co-N/C catalysts for the oxygen reduction reaction and identified a saturated metal content as a major limiting factor for further improvement of catalyst activity.

TL;DR: This critical review presents the current technological advances in proton exchange membrane (PEM) fuel cell catalysis, with a focus on strategies for developing nanostructured Pt-alloys as electrocatalysts for the oxygen reduction reaction (ORR).

TL;DR: In this paper, the effect of heat treatment on the catalytic activity and stability of proton exchange membrane (PEM) fuel cell catalysts is discussed. But, the authors do not consider the effects of temperature and time on the individual catalysts.

TL;DR: It has been identifi ed that the lithium intercalation in TiO 2 –B features a pseudocapacitive process, rather than the solid-state diffusion process observed for anatase and rutile, which results in fast chargedischarge capability of a lithium cell.
