Critical Review of Platinum Group Metal-Free Materials for Water Electrolysis: Transition from the Laboratory to the Market : Earth-abundant borides and phosphides as catalysts for sustainable hydrogen production
To combat the global problem of carbon dioxide emissions, hydrogen is the desired energy vector for the transition to environmentally benign fuel cell power. Water electrolysis (WE) is the major technology for sustainable hydrogen production. Despite the use of renewable solar and wind power as sources of electricity, one of the main barriers for the widespread implementation of WE is the scarcity and high cost of platinum group metals (pgms) that are used to catalyse the cathodic hydrogen evolution reaction (HER) and the anodic oxygen evolution reaction (OER). Hence, the critical pgm-based catalysts must be replaced with more sustainable alternatives for WE technologies to become commercially viable. This critical review describes the state-of-the-art pgm-free materials used in the WE application, with a major focus on phosphides and borides. Several emerging classes of HER and OER catalysts are reviewed and detailed structure-property correlations are comprehensively summarised. The influence of the crystallographic and electronic structures, morphology and bulk and surface chemistry of the catalysts on the activity towards OER and HER is discussed.
Los Alamos National Laboratory and Lawrence Livermore National Laboratory Plutonium Sustainment Monthly Program Report, October 2012 (Revision 8)
In October of 2012 the Plutonium Sustainment program at LANL completed or addressed the following high-level activities: 1) Completed Pollux shipment to DAF in early October in accordance with the Gemini Core Team's schedule. Unpacked Pollux at DAF and supported Gemini team in various tests and inspections. Pollux test and measurement results were all acceptable. Pollux is expected to g to U1A in November. Pu Sustainment no longer has any obligations associated with the Gemini experiment. 2) Presented to Dr. Cook on the successful assembly of the Pollux experimental device as part of the Gemini series. 3) Supported the release of the FY12 Pu Sustainment Program Implementation Plan. 4) Established the FY12 program baseline and allocated funds accordingly. 5) Meetings: a. Hosted the Pu Containment 4 th Quarter Program Review; b. Hosted the Power Supply PRT; c. Traveled to KCP for the W87 Pit IPT. All four MRT L2 Milestones (4622-4625) associated with Plutonium Sustainment are on track for success in FY13.
