UT El Paso-led team designs cactus-inspired low-cost, efficient water-splitting catalyst

Green Car Congress

Researchers led by engineers at The University of Texas at El Paso (UTEP) have proposed a low-cost, cactus-inspired nickel-based material to help split water more cheaply and efficiently. Nickel, however, is not as quick and effective at breaking down water into hydrogen. who led the study. —Attarzadeh et al.

Researchers use melamine to create effective, low-cost carbon capture; potential tailpipe application

Green Car Congress

Using an inexpensive polymer called melamine, researchers from UC Berkeley, Texas A&M and Stanford have created a cheap, easy and energy-efficient way to capture carbon dioxide from smokestacks. The low cost of porous melamine means that the material could be deployed widely. Haiyan Mao et al.

SwRI, UTSA researchers show biochar is low-cost, effective method to treat fracking water

Green Car Congress

Researchers at Southwest Research Institute (SwRI) and The University of Texas at San Antonio (UTSA) have determined that biochar, a substance produced from plant matter, is a safe, effective and inexpensive method to treat flowback water following hydraulic fracturing, or fracking. —Maoqi Feng, SwRI. —Zhigang Feng, USTA.

Sandia team boosts hydrogen production activity by molybdenum disulfide four-fold; low-cost catalyst for solar-driven water splitting

Green Car Congress

The improved catalyst has already released four times the amount of hydrogen ever produced by MoS 2 from water. To determine what was happening, and the best way to make it happen, the Sandia team used computer simulations generated by coauthor Na Sai from the University of Texas at Austin that suggested which molecular changes to seek.

University of Houston team demonstrates new efficient solar water-splitting catalyst for hydrogen production

Green Car Congress

Researchers from the University of Houston (UH) have developed a cobalt(II) oxide (CoO) nanocrystalline catalyst that can carry out overall water splitting with a solar-to-hydrogen efficiency of around 5%. The generation of hydrogen from water using sunlight could potentially form the basis of a clean and renewable source of energy.

UH team develops fast, cost-efficient method to grow OER catalyst for seawater splitting

Green Car Congress

A team of researchers led by Zhifeng Ren, director of the Texas Center for Superconductivity at the University of Houston, has developed an oxygen-evolving catalyst that takes just minutes to grow at room temperature on commercially available nickel foam. That requires substantial amounts of energy and drives up the cost.

Univ. of Texas researchers propose lithium- or sodium-water batteries as next generation of high-capacity battery technology; applicable for EVs and grid storage

Green Car Congress

Example of a lithium-water rechargeable battery. Researchers at the University of Texas, including Dr. John Goodenough, are proposing a strategy for high-capacity next-generation alkali (lithium or sodium)-ion batteries using water-soluble redox couples as the cathode. In theory, the decomposition potential of water is 4.27
