Direct methanol fuel cells have emerged as highly promising energy conversion devices in the past few decades. However, some challenges, such as carbon monoxide (CO) poisoning and unsatisfactory long-term stability, remain for platinum (Pt) as a methanol oxidation reaction (MOR) catalyst. This review covers recent advances in Pt alloy MOR catalysts and provides some insights. This review presents MOR catalytic mechanisms based on CO or non-CO pathways. Typical dimension-based designs of MOR catalysts, such as anisotropic nanowires, metallene, nanoframes, and corresponding rationales for performance enhancements, are introduced. More importantly, some key tuning strategies are elaborated, including intermetallic compound synthesis, interface engineering, and surface facet engineering. High-entropy alloys as an intriguing class of MOR catalysts with favorable prospects are also discussed. Finally, future directions and opportunities are outlined.

Electrocatalytic technology is essential to develop environmentally friendly energy technologies and to reduce dependence on non‐renewable resources. The construction of highly efficient, inexpensive, and robust electrocatalysts is the primary prerequisite to the large‐scale application of electrochemical devices. In recent years, selenium‐based catalysts (SBCs) have been extensively investigated and emerged as a promising candidate for electrocatalysis given their potential to reduce or replace the dosage of noble metals and their ability to catalyze a range of critical electrochemical processes. This Review minutely analyses the recent research advances in SBCs, highlighting the significant role of Se in enhancing the catalytic performance. First, it starts from the concepts related to SBCs, followed by the classification of SBCs as well as the strategies to regulate the activity of SBCs are elaborated. Then, the techniques for characterizing SBCs are systematically summed up, mainly focusing on morphological and structural characterization methods. Next, the applications of SBCs in various energy‐conversion reactions (e.g., hydrogen evolution reaction, oxygen evolution reaction, oxygen reduction reaction, nitrogen reduction reaction, CO2 reduction reaction) are discussed, aiming at elucidating the association between their structure–activity correlations. Finally, the challenges related to SBCs and their future development trends are presented.

The electrocatalytic oxidation of solketal (SOR) as the anodic reaction can be used to enhance hydrogen production efficiency due to its lower overpotential compared to the oxygen evolution reaction (OER). Additionally, solketal oxidation yields besides formate also high‐value C3 products, providing an advantage over the typical alternative reaction for OER, glycerol oxidation. The multi‐metal CoNiFeCu (1:1:1:0.5) catalyst is employed as electrocatalyst for SOR and different activation procedures are explored. The pre‐conditioning of the catalyst in the presence of solketal supports a current density of 10 mA cm−2 to be recorded at only 1.405 ± 1 mV versus reversible hydrogen electrode (vs. RHE) during SOR, while promoting glyceric acid synthesis with 40% faradaic efficiency. Operando attenuated total reflection Fourier‐transform infrared spectroscopy (ATR‐FTIR) confirms that the activation of the catalyst contributes to an increased formation of products. However, most importantly, through utilizing the single‐particle‐on‐the‐nanoelectrode with identical‐location transmission electron microscope (IL‐TEM), it is unveiled that solketal suppresses Cu leaching and oxyhydroxide formation. Moreover, the structural transformations are correlated with the increased activity toward SOR.
