“…Similarly, the pre-edge threshold position also indicates the absorption edge shifts to a lower energy (Figure 2i). [39] An extended X-ray absorption fine structure (EXAFS) analysis was conducted to quantitatively analyze the short-range atomic structure; the results are shown in Table S4 (Supporting Information). The Co K-edge k 3 𝜒 spectra demonstrate the weaker intensity of B-Co 3 O 4 -350 and B-Co 3 O 4 -350-R compared with that of Co 3 O 4 (Figure S12, Supporting Information), indicating the decreasing coordination sites in Co centers.…”

Optimally increasing the catalytic activity of Co3O4‐based materials is crucial for promoting their practical applications for acetone detection; however, this still remains challenging. Herein, a strategy is proposed in this work to increase the catalytic activity of Co3O4 toward the oxidation of acetone through the synergistic effect of boron doping and chemical reduction, which can substantially improve the sensing performance for acetone detection. The characterization results confirm that the present strategy facilitates the formation of more oxygen vacancies and increases the content of Co2+ ions serving as active sites. As expected, the optimal sensor yields a higher response . To extend the practical application to the auxiliary diagnosis of diabetes through exhaled breath, the optimal sensors distinguished between acetone concentrations in the breath of healthy individuals and in the simulated breath of patients with diabetes. Detailed gas‐sensing measurements reveal that the enhanced acetone sensing performance is attributed to the increased catalytic activity of materials for oxidation of acetone by the Mars–van Krevelen, Langmuir–Hinshelwood, and Eley–Rideal mechanisms. This study provides new insights into the fabrication of high‐performance metal oxide‐based gas sensors by improving the catalytic activity of sensing materials.

“…[ 45,46 ] Moreover, urea‐assisted water splitting process not only enables H 2 production but also treats the urea‐rich wastewater, which is also highly expected for environmental protection. [ 47 ] Urea oxidation reaction (UOR) process can be expressed as follows: [ 48,49 ] CO(NH 2 ) 2 + 6OH − → CO 2 + N 2 + 5H 2 O + 6e − . Theoretically, UOR only requires a thermodynamic potential of 0.37 V, which is remarkably lower than 1.23 V of OER.…”

Rational designing electrocatalysts is of great significance for realizing high‐efficiency H2 production in the water splitting process. Generally, reducing the usage of precious metals and developing low‐potential nucleophiles oxidation reaction to replace anodic oxygen evolution reaction (OER) are efficient strategies to promote H2 generation. Here, NiS‐coated nickel–carbon nanofibers (NiS@Ni‐CNFs) are prepared for low‐content Pt deposition (Pt‐NiS@Ni‐CNFs) to attain the alkaline HER catalyst. Due to the reconfiguration of NiS phase and synergistic effect between Pt and nickel sulfides, the Pt‐NiS@Ni‐CNFs catalyst shows a high mass activity of 2.74‐fold of benchmark Pt/C sample. In addition, the NiS@Ni‐CNFs catalyst performs a superior urea oxidation reaction (UOR) activity with the potential of 1.366 V versus reversible hydrogen electrode (RHE) at 10 mA cm−2, which demonstrates the great potential in the replacement of OER. Thus, a urea‐assisted water splitting electrolyzer of Pt‐NiS@Ni‐CNFs (cathode)||NiS@Ni‐CNFs (anode) is constructed to exhibit small voltages of 1.44 and 1.65 V to reach 10 and 100 mA cm−2, which is much lower than its overall water splitting process, and presents a 6.5‐fold hydrogen production rate enhancement. This work offers great opportunity to design new catalysts toward urea‐assisted water splitting with significantly promoted hydrogen productivity and reduced energy consumption.

“…Furoic acid is a vital feedstock in the agrochemical, pharmaceutical, organic synthesis, perfume, fragrance, and flavor industries. [ 12–14 ] Thus, recently, a few attempts have been dedicated to investigating the electrocatalytic oxidation of furfural coupled with HER, for example, Ni 3 N–V 2 O 3 , [ 15 ] Cu nanoparticles (NPs), [ 16 ] Pt/Au, [ 17 ] Cu 3 P nanosheets, [ 18 ] Ni 2 P/Ni arrays, [ 4 ] and NiFe oxide. [ 1 ] The efficiency of electrochemical reactions (HER and furfural oxidation reaction (FOR)) and the product yield of H 2 and furoic acid mainly depend on the electrocatalyst selected.…”

Here, furfural oxidation was performed to replace the kinetically sluggish O2 evolution reaction (OER). Pt‐Co3O4 nanospheres were developed via pulsed laser ablation in liquid (PLAL) in a single step for the paired electrocatalysis of an H2 evolution reaction (HER) and furfural oxidation reaction (FOR). The FOR afforded a high furfural conversion (44.2%) with a major product of 2‐furoic acid after a 2‐h electrolysis at 1.55 V versus reversible hydrogen electrode in a 1.0‐M KOH/50‐mM furfural electrolyte. The Pt‐Co3O4 electrode exhibited a small overpotential of 290 mV at 10 mA cm−2. As an anode and cathode in an electrolyzer system, the Pt‐Co3O4 electrocatalyst required only a small applied cell voltage of ∼1.83 V to deliver 10 mA cm−2, compared with that of the pure water electrolyzer (OER∥HER, ∼1.99 V). This study simultaneously realized the integrated production of energy‐saving H2 fuel at the cathode and 2‐furoic acid at the anode.
