Koalas were declared endangered in eastern Australia on Friday, with more and more koalas dying from disease, habitat loss, and other threats. Earlier, the koala was considered a vulnerable species, and the Commonwealth Department of the Environment changed its protection level to endangered on the east coast of Queensland, New South Wales, and the Australian Capital Territory. Many koalas in Australia are infected with chlamydia. The disease can cause blindness, infection, and infertility. Last year, the Australian Koala Foundation said Australia had lost about 30 percent of its koala population in the past three years. Without immediate action, the species could become extinct by 2050.
Unlike koalas, which are on the brink of extinction, the market demand for Cu2O powder will grow substantially.
Si and GaN are major players in semiconductor materials. One material that keeps coming up in research is cuprous oxide. Cuprous oxide is one of the first materials discovered to have semiconducting properties.
What is Cuprous Oxide?
Cuprous oxide is a semiconductor with a band gap ranging from 2.0 to 2.2eV and has photovoltaic characteristics. As a p-type oxide of copper with chemical formula Cu2O, it can exist in the form of thin films or nanoparticles and is very useful for basic research due to its low cost and new physical properties.
Over the past few decades, researchers have identified a variety of ways to synthesize cuprous oxide. Some of the techniques found were:
Chemical vapor deposition
Sol-gel dip coating technology
Even after extensive research, a significant barrier to the use of these methods is the generation of mixed phases of Cu, CuO and Cu2O, resulting in few applications for cuprous oxide as a semiconductor.
Cuprous Oxide Electronic Properties
Research on cuprous oxide has been ongoing to understand its electronic properties and potential as a semiconductor material.
A research team reports that when it is doped with 12.5% zinc, its optical properties are improved and can be used in photocatalytic and sensor devices. According to another group, the band gap was reduced from 1.96eV to 1.91eV when it was mixed with F element at a concentration of 0.34%.
However, its photovoltage and photocurrent density are increased to 0.4457V and 2.79mA/cm2, respectively.
Cuprous Oxide Application
Major applications of cuprous oxide in electronics include supercapacitors, lithium ion batteries, photocatalysis, solar energy conversion and sensing applications.
Electrodes for supercapacitors and lithium-ion batteries:
Cuprous oxide is suitable as an anode material for lithium-ion batteries because of its controllable structure, polymorphic form, and high cycling capacity.
Photocatalysis and solar energy conversion:
Due to the abundance of copper and oxygen in nature, appropriate visible light absorption band gaps, and relatively easy and inexpensive manufacturing, cuprous oxide is suitable for large-scale solar conversion.

With Russia taking the lead on Poland and Bulgaria at the end of last month, there appears to be a growing sense of compromise within the EU over whether to accept Moscow's proposed rouble settlement order.
Italy's prime minister said recently that European companies would be able to buy gas in roubles without violating sanctions. This apparently ignores the guidance of hardliners in the EU to "fight to the end".
For weeks, European companies have been trying to find ways to meet Russia's payment demands for the rouble while maintaining vital gas supplies without violating sanctions against Moscow.
Late last month, European Commission President Von der Leyen said operating under the mechanism would violate sanctions and asked European companies not to bow to Russian demands. However, the EU has yet to issue more rigorous written guidelines on how companies should pay Gazprom.
The Italian prime minister said recently, "There is no official announcement from the European Union about what ruble settlement means for sanctions violations, and no one has said whether ruble payments violate sanctions or not. It's a grey area."
"In fact, most gas importers are already opening rouble accounts for deals with Gazprom,"
He also used German companies as a shield. He said Germany's largest gas importer had already paid in rubles. "In fact, we saw evidence yesterday that the largest gas importer in Germany has already paid in rubles."
