To study the performance of two different anode catalysts, e.g., Pt-Au/C and Pt-Bi/C, at low metal loadings in batch and continuous type direct glucose fuel cell (DGFC), the metal catalysts were prepared and physical and electro-chemical characterizations were carried out. A continuous DGFC based on anion exchange membrane (AEM) electrolyte with Pt-Bi/C or Pt-Au/C as anode and Pt/C as cathode resulted in higher power densities than that of batch type DGFC with alkaline (KOH) electrolyte. The DGFC operated at ambient temperature (30 degrees C) with Pt-Bi/C anode produced higher maximum power density (MPD) (4.8 mW cm(-2)) compared to Pt-Au/C anode (MPD = 2.44 mW cm(-2)) with anode and cathode feed 4 ml min(-1) of 0.2 M glucose and 16 SCCM oxygen at 1 bar.

Aditya Singh, Biswajit Samir De, Sujay Karmakar, Suddhasatwa Basu

Summary: The WO3/BiVO4 heterojunction-based photoanodes have great potential in PEC water splitting. However, challenges such as resistive losses of TCO substrate and nonuniform deposition of co-catalyst hinder the development of large-area photoanodes. In this study, a patterned metal microgrid is used to reduce resistive losses and improve the uniformity of potential distribution. The combination of metal microgrid, large-area WO3/BiVO4 heterojunction, flow-induced uniform deposition of CoPi, and electrolyte flow in PEC cell design enhances the photocurrent and stability of large-area photoanodes. This research provides guidelines for improving the PEC performance of large-area photoanodes through electrochemical engineering strategies.

Prediction of phosphate adsorption amount, capacity and kinetics via machine learning: A generally physical-based process and proposed strategy of using descriptive text messages to enrich datasets

Baiqin Zhou, Huiping Li, Ziyu Wang, Hui Huang, Yujun Wang, Ruichun Yang, Ranran Huo, Xiaoyan Xu, Ting Zhou, Xiaochen Dong

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
