• Bottom-Up Fabrication of Oxygen Reduction Electrodes with Atomic Layer Deposition for High-Power-Density PEMFCs 

      Dull, Sam; Xu, Shicheng; Goh, Timothy; Lee, Dong Un; Higgins, Drew; Orazov, Marat; Koshy, David; Vullum, Per Erik; Kirsch, Sebastian; Huebner, Gerold; Torgersen, Jan; Jaramillo, Thomas F; Prinz, Friedrich (Journal article, 2021)
      As the platinum (Pt) loading in proton exchange membrane fuel cell cathodes is driven down to reduce costs, catalyst utilization becomes increasingly important. Here, we report an atomic layer deposition-facilitated electrode ...
    • Direct Integration of Strained-Pt Catalysts into Proton-Exchange-Membrane Fuel Cells with Atomic Layer Deposition 

      Xu, Shicheng; Wang, Zhaoxuan; Dull, Sam; Liu, Yunzhi; Lee, Dong Un; Pacheco, Lezama; Orazov, Marat; Vullum, Per Erik; Dadlani, Anup; Vinogradova, Olga; Schindler, Peter; Tam, Qizhan; Schladt, Thomas; Mueller, Jonathan E.; Kirsch, Sebastian; Huebner, Gerold; Higgins, Drew; Torgersen, Jan; Viswanathan, Venkatasubramanian; Jaramillo, Thomas F; Prinz, Friedrich (Peer reviewed; Journal article, 2021)
      The design and fabrication of lattice-strained platinum catalysts achieved by removing a soluble core from a platinum shell synthesized via atomic layer deposition, is reported. The remarkable catalytic performance for the ...
    • Extending the limits of Pt/C catalysts with passivation-gas-incorporated atomic layer deposition 

      Xu, Shicheng; Kim, Yongmin; Park, Joonsuk; Higgins, Drew; Shen, Shih-Jia; Thian, Dickson; Provine, John; Torgersen, Jan; Graf, Tanja; Schladt, Thomas; Orazov, Marat; Liu, Bernard Haochih; Prinz, Fritz (Journal article; Peer reviewed, 2018)
      Controlling the morphology of noble metal nanoparticles during surface depositions is strongly influenced by precursor–substrate and precursor–deposit interactions. Depositions can be improved through a variety of means, ...
