Common Pt-based electrocatalysts have the disadvantages of high cost and easy deactivation. The research focus will be the development of carbon-based counter electrodes (CEs) due to the high conductivity and stability in the electrolytes. This paper prepares a kind of CE with wood-derived pore-rich carbon (WDPRC), which uses poplar as the precursor and activates with KOH at different temperatures (700, 800, and 900 degrees C). 800-WDPRC (800 represents temperature) had a large specific surface area of 1234.30 m2/g, which shows that it has a rich pore structure, and provides more active sites ...
