“…It is of great interest to prepare novel solid acid catalysts from new materials and investigate the relationship between catalyst structure, treatment conditions and catalytic performance. Willow catkins are a kind of biomass waste, which were widely used as template in preparation of carbon microtubes due to their natural microtubular structure applied in supercapacitors [22,23]. However, there is no report on the preparation of sulfonated carbon catalysts based on catkin and its associated performance in catalytic reactions.…”

Highly porous carbon microflakes (CMFs) with oxygen and nitrogen dual-doping were prepared from willow catkins by pyrolysis at 500 C in nitrogen, followed by KOH activation and were used as a highperformance supercapacitor electrode material. The as-prepared CMFs with a thickness of 350 nm possess an incredibly high specific surface area of 3510 m 2 g À1 and a large pore volume of 2.1 cm 3 g À1 .The CMFs exhibit a high specific capacitance (for a three-electrode system) of 372, 344 F g À1 at 1 A g À1 in 2 M H 2 SO 4 and 6 M KOH, respectively. The specific capacitance is 278 F g À1 at 1 A g À1 in a twoelectrode system (2 M H 2 SO 4 electrolyte). The CMFs electrode demonstrates good rate capability with retention of 79.6% (from 1 A g À1 to 20 A g À1 ) and excellent cycling stability with 95% capacity retention after 5000 cycles. The CMFs symmetric device shows a high energy density of 9.5 W h kg À1 at a power density of 500 W kg À1 in H 2 SO 4 .Scheme 1 illustrates a schematic diagram for the preparation of porous carbon from willow catkins.

Searching for non‐precious electrocatalysts with high performance to replace the expensive Pt‐based electrocatalysts for oxygen reduction reaction (ORR) is a key issue in the industrial‐scale application of fuel cells. In this study, we have reported the synthesis of an iron doped N‐containing carbon materials, derived from duck blood, a wasted material in the duck meat production, as a novel and cost‐effective catalyst in ORR. The as‐prepared electrocatalysts were characterized by means of powder X‐ray diffraction, scanning electron microscopy, Raman spectroscopy and X‐ray photoelectron spectrometer. In 0.1 mol L−1 KOH solution, the ORR onset potential and the half‐wave potential for the iron doped N‐containing carbon materials are 33 mV and –120 mV respectively, which are close to those of commercial Pt/C (20 wt%). In addition, the iron doped N‐containing carbon materials exhibit excellent tolerance to methanol crossover, which makes it a promising electrocatalyst for ORR in fuel cell.
