“…Among these Fe‐N‐GDY catalysts, the 1.5 %Fe‐N‐GDY exhibited the highest activity for ORR, almost similar with commercial Pt/C (JM), but with higher stability and methanol tolerance than that of Pt/C. Compared with other M‐N‐C catalyst materials, the 1.5 %Fe‐N‐GDY performed the catalysis more efficiently …”

On account of the high‐cost of platinum, researchers are working to develop a new catalyst that is cheaper and has a catalytic effect equivalent to platinum. Herein, owing to the unique acetylenic bonds in graphdiyne, iron, nitrogen co‐doped graphdiyne (Fe‐N‐GDY) is a promising nonprecious metal catalyst, which has been developed with just a small amount of iron precursor with the plan to substitute it for Pt‐based catalysts. The as‐synthesized Fe‐N‐GDY composited catalyst shows excellent catalytic performance with the onset potential of 0.94 V versus reversible hydrogen electrode and limited current density of 5.4 mA cm−2. Moreover, it shows excellent resistance to methanol poisoning and stability in both acidic and alkaline electrolytes, which makes potentially applicable in the oxygen reduction reaction field.

“…From then on, nitrogen‐doped carbon nanotubes, nitrogen‐doped graphene, C 3 N 4 , and other carbon‐based materials became the research focus in the field of electrocatalysis . Besides N atoms, other non‐metal atoms such as S, B, and P as well as the transition metal atoms such as Fe, Co, Ni, and Cu have been chosen as the heteroatoms in carbon materials to form doped catalysts for ORR . It is reported that the high catalytic activity and stability of the catalysts pyrolyzed at high temperature arise from the active sites such as Fe, FeN x , FeO x , and FeC, which makes the heteroatom‐doped carbon materials have comparable catalytic performances with Pt‐based catalysts .…”

Summary A series of non‐precious metal FexNC electrocatalysts for oxygen reduction reaction (ORR) were successfully synthesized using Fe(NO3)3, glucose, and melamine as the Fe, C, and N sources, respectively. The effects of the pyrolysis temperature and Fe/N contents on the catalytic performances are comprehensively investigated. Electrochemical results reveal that among the FexNC catalysts, Fe1.5NC‐900‐2 pyrolyzed at 900°C with the mass ratio of FeC to melamine being 1:10 proves the highest catalytic performance. The half‐wave potential (E1/2) of ORR was 821 mV (vs reversible hydrogen electrode (RHE)) and only 36 mV lower than that on commercial Pt/C catalyst (857 mV). More importantly, Fe1.5NC‐900‐2 catalyst shows excellent stability and methanol tolerance. After 1000 sequential cycles, the E1/2 on Pt/C catalyst shifts negatively by approximately 60 mV, while for Fe1.5NC‐900‐2 catalyst, this shift is only 28 mV although the number of sequential cycles is increased to 8000. In the presence of methanol, the current decay in the chronoamperometric response at 1000 seconds is only 8% and also much lower than that on Pt/C catalyst (46%). The high catalytic performances arise from the abundant Fe3N active sites embedded in the carbon matrix of the FexNC catalysts. These findings can be used to discuss the catalytic mechanism of ORR on the FexNC catalysts and design the nonprecious metal carbon‐based electrocatalysts for ORR.

“…However, these materials can also be utilized as sources of the production of porous carbon materials. In fact, carbon materials derived from biomass have already been used in the fields of supercapacitors [6,7], catalysis [8], electrocatalysis [9], adsorption of dyes and heavy metal ions [10], and so on.…”

A porous carbon material was prepared from quinoa husk (QH) by carbonization and chemical activation with KOH. A series of experiments, including SEM (Scanning electron microscopy), FT-IR (Fourier transform infrared), XRD (X-ray diffraction), Raman, X-ray photoelectron spectroscopy (XPS), and N2 adsorption/desorption, were carried out on the porous carbon produced from quinoa husk (PC–QH). The results showed that PC–QH was mainly composed of activated carbon and graphite. Moreover, PC–QH exhibited a high level of porosity with a BET (the Brunauer–Emmett–Teller theory) surface area of 1713 m2 g−1. As a representative dye, malachite green (MG) was selected to evaluate the performance of PC–QH to absorb the contaminants in dyeing wastewater. In batch adsorption experiments, PC–QH exhibited a high adsorption rate toward malachite green (MG). An uptake capacity of 599.90 mg g−1 was achieved in the initial 5 min, and the MG adsorption capacity of PC–QH reached 1365.10 mg g−1, which was higher than many other adsorbents. The adsorption data were well fitted with the Freundlich isotherm model and the pseudo-second-order kinetic model. PC–QH also displayed a high absorption rate to rhodamine B (RhB), methyl violet (MV), methylene blue (MB), and methyl orange (MO). The results in this study suggest that PC–QH can be a promising adsorbent for quick treatment of dyeing wastewater.
