Stanford's water-splitting catalyst

Of all sources, Scott Adams linked this, but my server blocked it, although Google Cache led me to https://www.nature.com/articles/ncomms8261, and then Google sent me to Green Car Congress: Stanford team develops new low-voltage single-catalyst water splitter for hydrogen production

Has anyone heard of this? How significant is it?

the new catalyst achieved 10 mA cm−2 water-splitting current at only 1.51 V for more than 200 h
Equal to the noble metal catalysts.

Quote:
Breaking down metal oxide into tiny particles increases its surface area and exposes lots of ultra-small, interconnected grain boundaries that become active sites for the water-splitting catalytic reaction. This process creates tiny particles that are strongly connected, so the catalyst has very good electrical conductivity and stability.

This nano-scale assembling sounds similar to the way they are assembling miniaturized perovskite solar cells:

Inverse:"Solar Tarps" May Be the Alternative to Expensive Tesla Solar Roofs

So now I guess I need to read Scott Adams blog, in addition to Coffee with Scott Adams on Youtube: Homes Above, Tunnels Below | Scott Adams' Blog

I cannot keep track of these cutting-edge solar and battery technologies that are perpetually 5-10 years away, but it looks like you mentioned this one!

Here is the actual link: https://www.independent.co.uk/tech/s...-b2062365.html

However, that is behind a paywall, so this is the link to the weird service that gives me notifications: https://share.newsbreak.com/xxh2itk9

The chemists were able to overcome perovskite’s difficult properties by making use of a metal-containing material called ferrocenes, which they added as an interface betewen the light-absorbing layer of the solar cell and the layer that transports electrons.
