Photoelectrocatalytic nanomaterials are promising for direct alcohol fuel cells, but the construction of high-efficiency catalysts remains difficult. We herein successfully synthesized three-dimensional (3D) PdM nanosheet assemblies (PdM NSAs, M = Au, Ag, and Cu) through a seed-mediated growth method, which displayed a typical 3D nanoflower morphology assembled from many two-dimensional ultrathin nanosheets. Due to the open 3D structure and the synergistic and electronic effects between Pd and Ag, the optimized PdAg NSAs showed the highest mass activity (9378 mA mg–1) for the ethylene glycol oxidation reaction. More interestingly, when irradiated with visible light, the mass activity increased to 14 590 mA mg–1, 12.1 times higher than that of the commercial Pd/C (1205 mA mg–1). In addition, the as-obtained catalysts also showed better long-term durability than that of the commercial Pd/C under the condition of with or without visible-light illumination. This work highlights the utilization of light energy in designing excellent photoelectrocatalysts to promote the photoelectrocatalytic performance of anode catalysts for fuel cells.

“…The pinch technology for designing HENs and utilities has been widely used due to the contribution of the graphical representation of heat demands and heat sources with cumulative curves as a function of temperature . Therefore, a number of theoretical analysis methods and advanced technologies have been proposed and applied to improve the exergy utilization of energy-intensive chemical industries due to the energy shortage and stringent environmental requirements. − The HEN for the process of methanol synthesis by adding triple CO 2 feeds is utilized to achieve further energy-saving qualitatively.…”

The process of synthesizing syngas with the triple CO2 feeds is proposed to achieve an efficient use of CO2 that mitigates climate warming. Also, the amount of CO2 added in three locations as the variables of the process is optimized based on the CO2 conversion rate and the energy consumption per unit product (ECP) output flow rate by the genetic algorithm. The performances of the triple CO2 feeds in the methanol synthesis process had been evaluated by comparing with the traditional methanol production processes. To further reduce energy consumption, the irreversibility of each component and the locations of the inefficiency in the overall selected production process are studied on the basis of the exergy analysis. Pinch analysis is further used to find the optimal matching scheme. Compared with those of the proposed process, the energy consumption and the total exergy loss of the heat-integrated process are significantly reduced by 33.1 and 6.65%, respectively. Besides, the overall total annual cost is reduced by 10.1% and the cost of utilities is saved by 36.4%, which results in energy-saving.
