Solar material for producing clean hydrogen fuel



Osaka University researchers create new material based on gold and black phosphorus to produce clean hydrogen fuel using the full spectrum of sunlight

Global climate change and the energy crisis mean that alternatives to fossil fuels are urgently needed. Among the cleanest low-carbon fuels is hydrogen, which can react with oxygen to release energy, emitting nothing more harmful than water (H2O) as the product. However, most hydrogen on earth is already locked into H2O (or other molecules), and cannot be used for power.

Hydrogen can be generated by splitting H2O, but this uses more energy than the produced hydrogen can give back. Water splitting is often driven by solar power, so-called "solar-to-hydrogen" conversion. Materials like titanium oxide, known as semiconductors with the wide band-gap, are traditionally used to convert sunlight to chemical energy for the photocatalytic reaction. However, these materials are inefficient because only the ultraviolet (UV) part of light is absorbed -- the rest spectrum of sunlight is wasted.

Now, a team in Osaka University has developed a material to harvest a broader spectrum of sunlight. The three-part composites of this material maximize both absorbing light and its efficiency for water splitting. The core is a traditional semiconductor, lanthanum titanium oxide (LTO). The LTO surface is partly coated with tiny specks of gold, known as nanoparticles. Finally, the gold-covered LTO is mixed with ultrathin sheets of the element black phosphorus (BP), which acts as a light absorber.

"BP is a wonderful material for solar applications, because we can tune the frequency of light just by varying its thickness, from ultrathin to bulk," the team leader Tetsuro Majima says. "This allows our new material to absorb visible and even near infrared light, which we could never achieve with LTO alone."

By absorbing this broad sweep of energy, BP is stimulated to release electrons, which are then conducted to the gold nanoparticles coating the LTO. Gold nanoparticles also absorb visible light, causing some of its own electrons to be jolted out. The free electrons in both BP and gold nanoparticles are then transferred into the LTO semiconductor, where they act as an electric current for water splitting.

Hydrogen production using this material is enhanced not only by the broader spectrum of light absorption, but by the more efficient electron conduction, caused by the unique interface between two dimensional materials of BP and LTO. As a result, the material is 60 times more active than pure LTO.

"By efficiently harvesting solar energy to generate clean fuel, this material could help to clean up the environment," Majima says. "Moreover, we hope our study of the mechanism will spur new advances in photocatalyst technology."

Finally i want to introduce one product produced by Renogy company. Renogy 30A PWM Charge Controller is a very nice controller, easy to install and very well made. It can be used with a 12V battery or battery bank.

After this, you search for a site and appearance at some photos as well as the seller describes the view being a Day Sapphire Crystal. In reality what you don't learn is that the vendor submitted a type 1500 Plastic Gem Low-Swift and customized it with a sapphire gem. In another concept, the owner is providing a considerably pre-owned Rolex watches for sale making you imagine the purchase price is excellent when it's basically expensive.

The first the numbers of the serial number will allow you to choose what year the vintage Rolex watches was made. Thus if you have to decide for example looking at pictures between two watches that look similar and comparable value then a serial number would be a good determining factor.

Sometimes sellers merely fit one picture of the used Rolex watches, then it is a good idea to request more images including one of many back events, of the diamond, and the motion. Since you don't have the view in your hands it'd be the best way to acquire a sensation of how good condition the watch is in.

6 Reasons Your Business Won't Make You Rich



There are many reasons to enter the world of entrepreneurship, but the one that seems to draw the most newcomers is the prospect of "getting rich."

No wonder why so many people strive to own their own businesses for a shot at that big bank account. But it’s unlikely that merely owning a business is going to earn you the riches you seek. Here’s why:
