Efficient hydrolysis using Chromium and Cobalt on seawater February 4, 2023
Posted by stuffilikenet in Awesome, Geek Stuff, Science.add a comment
Right. A Chinese team has performed direct electrolysis of untreated seawater, achieving long-term stability exceeding 100 hours at 500 mA cm−2 and performance similar to a typical PEM electrolyzer operating in high-purity water. This is achieved by introducing a Lewis acid layer (for example, Cr2O3) on transition metal oxide catalysts to dynamically split water molecules and capture hydroxyl anions. Such in situ generated local alkalinity facilitates the kinetics of both electrode reactions and avoids chloride attack and precipitate formation on the electrodes. A flow-type natural seawater electrolyzer with Lewis acid-modified electrodes (Cr2O3–CoOx) exhibits the industrially required current density of 1.0 A cm−2 at 1.87 V and 60 °C. Managing this without filtering the seawater or alkalizing it first is the real key, here. The efficiency is near 100%, the first step towards green hydrogen production at scale. You are seeing the first glimpse of the sun-fueled future, where solar power is stored as hydrogen.

A company was founded by Hjalmar Nilsonne and Daniel Ek has created a 360-degree body scanner comes equipped with over 70 sensors that collect more than “50 million data points on skin, heart, vessels, respiration, microcirculation and more.” This data is then analyzed by a “self-learning AI-powered system” created by Neko Health.
This sort of thing seems vaguely familiar.
