    Aging gracefully? Investigating iridium oxide ink’s impact on microstructure, catalyst/ionomer interface, and PEMWE performance

    In this study, we conducted a thorough investigation of the impact of aging iridium oxide (IrO2) perfluorosulfonic acid ionomer ink for up to 14 days on the properties of the ink and the resulting catalyst layers. We examined ink properties, such as zeta potential, dynamic light scattering (DLS), density, surface tension, and rheology, as functions of ink aging time. To ev…

    The Conventional Gas Diffusion Electrode May Not Be Resistant to Flooding during CO2/CO Reduction

    The electrochemical CO2 or CO reduction to chemicals and fuels using renewable energy is a promising way to reduce anthropogenic carbon emissions. The gas diffusion electrode (GDE) design enables low-carbon manufacturing of target products at a current density (e.g., 500 mA cm−2) relevant to industrial requirements. However, the long-term stability of the GDE is restricted…

    In Situ Reconstructed Mo-doped Amorphous FeOOH Boosts the Oxygen Evolution Reaction

    Developing a fast and highly active oxygen evolution reaction (OER) catalyst to change energy kinetics technology is essential for making clean energy. Herein, we prepare three-dimensional (3D) hollow Mo-doped amorphous FeOOH (Mo-FeOOH) based on the precatalyst MoS2/FeC2O4 via in situ reconstruction strategy. Mo-FeOOH exhibits promising OER performance. Specifically, it ha…

    Pre-combustion mercury removal with co-production of hydrogen via coal electrolysis

    Pre-combustion mercury removal via coal electrolysis was performed and investigated on a bench-scale coal electrolytic cell (CEC) systemically, and factorial design was used to determine the effect of different operating conditions (coal particle size, operating temperature, operating cell voltage, and flow rate of slurry) on the percentage of mercury removal, percentage o…

    Development of a universal method for high yield of furfural and hydrogen from raw lignocellulosic biomass

    In order to develop a universal method for the co-production of furfural and hydrogen from raw lignocellulosic biomass, three types of substrates (maple wood, wheat straw, and tall fescue) were investigated, integrating chemical and electrochemical technologies. The results show both furfural and pure hydrogen were produced from all the biomass substrates, and the substrat…

    Assessment of lignite upgrade and hydrogen evolution via electrolysis

    Lignite, considered as the lowest-rank coal, accounts for 45% of the total coal resources worldwide, and its low carbon and high ash contents limit its large-scale application. In order to upgrade lignite effectively, a modified coal electrolytic cell (MCEC) was designed, built, and then evaluated for lignite upgrade and hydrogen production through electrolysis, and the op…
