The father of lithium batteries-John B. Goodenough

John B. Goodenough is one of the winners of the 2019 Nobel Prize in Chemistry and is known as the "Father of Lithium Batteries". He is the inventor of the three most important cathode materials for lithium-ion batteries, lithium cobaltate, lithium manganate and lithium iron phosphate, and has made great contributions to the development of lithium-ion batteries. He is currently a professor of mechanical engineering and materials science at the University of Texas at Austin. He is also a member of the National Academy of Engineering, a member of the National Academy of Sciences, a member of the French Academy of Sciences, and a member of the Royal Spanish Society. John B. Goodenough is the oldest Nobel Prize winner (97 years old) at the time of the award, breaking the record of Arthur Yahikin (96 years old).

The father of graphene-Andre Geim

Andre Geim is a professor at the University of Manchester. While teaching at the University of Manchester in 2004, Andre Geim and Konstantin Novoselov discovered the carbon atom structure of a two-dimensional crystal, which is the famous graphene. This discovery not only won him the Nobel Prize in Physics in 2010, but also made him the "father of graphene."

The father of OLED-Deng Qingyun

Ching W. Tang is a Chinese-American material physicist and chemist, a member of the National Academy of Engineering, a founding member of the Hong Kong Academy of Sciences, a member of the Hong Kong Academy of Engineering, and the first Chinese winner of the Wolf Prize in Chemistry, the Hong Kong University of Science and Technology Jockey Club Professor of the Bank of East Asia, Institute of Advanced Studies, Director of the State Key Laboratory of Advanced Display and Optoelectronics Technology.

The Organic Light Emitting Display (OLED) technology invented by Deng Qingyun in 1987 is a representative of the third generation of display technology after cathode ray tube (CRT) technology and liquid crystal display (LCD) technology. It has been widely recognized by the industry in more than ten years and is considered to be the "most ideal display technology for mankind". Professor Deng is therefore honored as the "Father of OLED".

The father of sensitized solar cells-Michael Gr?tzel

Michael Grötzel is currently a professor at the Federal Institute of Technology in Lausanne, leading the photonics and interface laboratory. He is a pioneer in the study of electron transfer reactions and energy in mesoscopic materials and their optoelectronic applications. In 1988, he and Brian O'Regan jointly invented a new type of solar cell based on dye-sensitized mesoscopic oxide particles. This battery is also called "Gr?tzel battery".

According to Google Scholar, Michael Grötzel has been cited up to 376,422 times and his H factor is 267. He is also one of the most cited scientists in the world.

The father of photocatalysis-Akira Fujishima

Akira Fujishima is a special honorary professor at the University of Tokyo and the chairman of the Kanagawa Institute of Science and Technology. He published in Nature in 1972 on the photolysis of water on the surface of titanium dioxide single crystals under ultraviolet light. This pioneering scientific research achievement known as the Honda-Fujishima effect and a series of subsequent important achievements made Akira Fujishima Recognized as the "father of photocatalysis".

According to Google Scholar, Akira Fujishima has been cited as high as 13,2018, and the H factor is 138.

The history of the field of photocatalysis can be traced back more than 80 years ago, mainly the early observation of the pulverization phenomenon of titanium dioxide-based coatings and the study of the blackening of metal oxides in contact with organic compounds in the sun. In the past 20 years, it has become a very intensive research field due to the effects of air and water repair, self-cleaning surfaces and self-sterilizing surfaces. During the same period, researchers have been working hard to use photocatalysis for light-assisted production of hydrogen. The fundamental aspects of photocatalysis on titanium dioxide, the most studied photocatalyst, are still under active research and have recently been widely understood. However, certain aspects (such as the phenomenon of photowetting) are still controversial. Some of them believe that this effect is a simple decomposition of organic pollutants, while others believe that there are other effects, including the inherent surface properties. Modified by light. In the past few years, some effective tools, such as surface spectroscopy technology and scanning probe technology performed on single crystals under ultra-high vacuum, and ultrafast pulsed laser spectroscopy technology, can solve these problems, and new insights are also available. Becomes possible. In addition, quantum chemical calculations also provide new insights. Recently, new materials have been developed based on titanium dioxide, and the sensitivity to visible light has been improved. In this review, the author provides an overview of some highlights, while reviewing some origins, and pointing out some possible new directions.
