Due to their biocompatible, sustainable and maintenance-free properties, they hold the promise as attractive energy sources for powering next generation medical electronics for personalized healthcare. Low current and power output are main bottlenecks of enzymatic biofuel cells to hinder their practical applications. Supercapacitors are able to harness ambitious energy and deliver high-power pulses. Combining enzymatic biofuel cells with supercapacitors to establish self-charging energy-conversion/energy-storage hybrid systems are considered as an effective strategy to improve the current and power output. This design enables the hybrid electric devices to scavenge ambient energy and simultaneously store it and thus increases the efficiency and facilitates the miniaturization for practical application. In this review, we first discuss various structural configurations of these self-charging hybrid systems, and then focus on explaining their charge storage mechanisms, including electrochemical double-layer capacitance, pseudocapacitance and hybrids. Several proof-of-concept applications as implantable and wearable power sources are enumerated.

In contrast to traditional fossil energy, fuel cells, through specific transformation routes, can generate more energy and reduce pollution under the same conversion relationship. Direct alcohol fuel cells, as a type of proton exchange membrane fuel cell, exhibit relatively superior performance. During the process of converting chemical energy into electrical energy, the conversion efficiency of the electrode is a crucial aspect of the fuel cell′s performance, thereby giving rise to electrode electrocatalysis. Nevertheless, the noble metal catalysts employed in current direct alcohol fuel cells are confronted with issues such as high cost, susceptibility to poisoning, and poor durability. A new approach to these problems is urgently needed. Loading noble metals onto metal oxides has been verified as an effective means. Among them, tin dioxide has attracted the attention of researchers due to its outstanding stability, anti-toxicity, and its positive auxiliary role in electrocatalysis. This article will conduct a review of the research progress in loading noble metals on tin dioxide carriers for the electrocatalytic oxidation of small molecule alcohols from various microstructures and loading methods.
