Daniel Kwabena Dakwa Bediako is a Ghanaian-British chemist. He is currently assistant professor at the University of California, Berkeley, and is the Cupola Era Professor in the college of chemistry. His research considers charge transport and interfacial charge transfer in two-dimensional materials and heterostructures. He is also a member of the Editorial Advisory Board of the Journal of the American Chemical Society (JACS) . [1]

Early life and education

Bediako was born in Accra, Ghana in 1986 to Kwame Bediako, a Ghanaian, and Gillian Mary Bediako, British. [2] [3] He grew up in Akropong, Ghana, but also spent portions of his childhood in Edinburgh. [2] Bediako was a student at the Akosombo International School through elementary and high school. During his time at high school, Bediako became interested in chemistry and was influenced by his high school chemistry teacher.

In 2004, he moved to the United States to attend Calvin University as an undergraduate student. [3] [4] At Calvin University, Bediako did research with Douglas Vander Griend, an inorganic chemistry professor, and became interested in inorganic coordination chemistry. [2] He graduated with honors in 2008, and joined UOP LLC to study new catalysts for industrial applications. [3]

After a year in industry, Bediako moved to the East Coast, where he joined the laboratory of Daniel G. Nocera at the Massachusetts Institute of Technology. Bediako eventually earned his master's degree at MIT, where he worked on mechanistic studies of water splitting electrocatalysis, and the development of metal catalysts for solar energy storage. [5] At MIT, he also worked on devices that use electricity from photovoltaic cells to generate hydrogen than can be used in fuel cells, and was part of the team who developed the components of the artificial leaf; a device which makes use of bacteria to convert solar energy into a liquid fuel. [6] [7] When Nocera moved to Harvard University, Bediako moved with him, and completed his doctoral research on the catalytic behavior of structurally disordered first row transition metal oxides. [2] [8]

Research and career

After completing his doctorate, Bediako remained at Harvard University as a postdoctoral research fellow in Philip Kim's group. Here he looked at quantum transport through two-dimensional van der Waals heterostructures. [3] [9] Here he focused on isolating ultra-thin layers of materials and precisely positioning them into a super-structure. [2] [10] By stacking materials in such a way, and embedding lithium ions between the individual layers, Bediako showed that it was possible to engineer higher electrochemical capacities. [10] [9]

In 2018, Bediako started a faculty position at the University of California, Berkeley. [2] He has been awarded an Office of Naval Research Young Investigator Award, [11] a United States Air Force Young Investigator Award [12] and a United States Department of Energy Early Career Award. [13] [14] He received the CIFAR Azrieli Global Scholar award in 2020. [15]

Artificial photosynthesis is a chemical process that biomimics the natural process of photosynthesis. The term artificial photosynthesis is used loosely, referring to any scheme for capturing and then storing energy from sunlight by producing a fuel, specifically a solar fuel. An advantage of artificial photosynthesis would be that the solar energy could converted and stored. By contrast, using photovoltaic cells, sunlight is converted into electricity and then converted again into chemical energy for storage, with some necessary losses of energy associated with the second conversion. The byproducts of these reactions are environmentally friendly. Artificially photosynthesized fuel would be a carbon-neutral source of energy, but it has never been demonstrated in any practical sense. The economics of artificial photosynthesis are noncompetitive.

<span class="mw-page-title-main">Electrolysis of water</span> Electricity-induced chemical reaction

Electrolysis of water is using electricity to split water into oxygen and hydrogen gas by electrolysis. Hydrogen gas released in this way can be used as hydrogen fuel, but must be kept apart from the oxygen as the mixture would be extremely explosive. Separately pressurised into convenient 'tanks' or 'gas bottles', hydrogen can be used for oxyhydrogen welding and other applications, as the hydrogen / oxygen flame can reach approximately 2,800°C.

<span class="mw-page-title-main">Electrocatalyst</span> Catalyst participating in electrochemical reactions

An electrocatalyst is a catalyst that participates in electrochemical reactions. Electrocatalysts are a specific form of catalysts that function at electrode surfaces or, most commonly, may be the electrode surface itself. An electrocatalyst can be heterogeneous such as a platinized electrode. Homogeneous electrocatalysts, which are soluble, assist in transferring electrons between the electrode and reactants, and/or facilitate an intermediate chemical transformation described by an overall half reaction. Major challenges in electrocatalysts focus on fuel cells.

The electrochemical reduction of carbon dioxide, also known as CO2RR, is the conversion of carbon dioxide to more reduced chemical species using electrical energy. It represents one potential step in the broad scheme of carbon capture and utilization.

In fuel cells, the reduction to water is preferred because the current is higher. The oxygen reduction reaction is well demonstrated and highly efficient in nature.
