Ammonia is one of the most critical chemical commodities produced and is integral to a number of current industries such as agriculture as well as a key part to future sustainability areas such as clean H2 production. However, the current production methods for ammonia are largely unsustainable and produce large amounts of CO2 emissions. This combined with the current dependence on fossil energy for production has led to researchers attempting to develop a clean and sustainable method for ammonia production. This method involves the thermochemical looping of a nitride compound with H2, and the renitridation of the compound with N2. This thermochemical loop would significantly reduce pressure requirements for ammonia production in addition to only being reliant on renewable inputs. This paper expands and complements this research by detailing the methods for the synthesis of nitride compounds as well as confirming their structure through material characterization. The nitride compounds as well as their oxide precursors were synthesized through Pechini synthesis and co-precipitation, and their structure was confirmed through the use of X-ray diffraction analysis. The XRD patterns of the synthesized nitrides matched those previously synthesized as well as those found in literature. In addition, observation of the spectra for the oxide CoMoO4 showed a marked similarity to that of the oxide precursor for (NixCox)2Mo3N. However, further testing is necessary regarding the phase-purity of synthesized nitrides, as well as the reduction and renitridation capability of nitrides in the line of (NixCox)2Mo3N.

The goal of this research was to identify why the federal government should invest in solar research and development, and which areas of solar improvement should be focused on. Motivation for this can be found in the pressing need to prevent and reverse the effects of climate change, the inevitability of fossil fuel resources eventually running out, and the economic and job creation potential which solar energy holds. Additionally, it is important to note that the best course of action will involve a split of funding between current solar rollout and energy grid updating, and the R&D listed in this research. Upon examination, it can be seen that an energy revolution, led by a federal solar jobs program and a Green New Deal, would be both an ethically and economically beneficial solution. A transition from existing fossil fuel infrastructure to renewable, solar-powered infrastructure would not only be possible but highly beneficial in many aspects, including massive job creation, a more affordable, renewable energy solution to replace coal-fired plants, and no fuel spending or negotiation required.<br/>When examining which areas of solar improvement to focus on for R&D funding, four primary areas were identified, with solutions presented for each. These areas for improvement are EM capture, EM conversion efficiency, energy storage capacity, and the prevention of overheating. For each of these areas of improvement, affordable solutions that would greatly improve the efficiency and viability of solar as a primary energy source were identified. The most notable area that should be examined is solar storage, which would allow solar PV panels to overcome their greatest real and perceived obstacle, which is the inconsistent power generation. Solar storage is easily attainable, and with enough storage capacity, excess solar energy which would otherwise be wasted during the day can be stored and used during the night or cloudy weather as necessary. Furthermore, the implementation of highly innovative solutions, such as agrivoltaics, would allow for a solar revolution to occur.
