Power‐to‐Syngas – eine Schlüsseltechnologie für die Umstellung des Energiesystems?

Within this context, the utilization of renewable energy is gaining increasing interest. One important aspect is the storage of electrical energy. The different applications to store electrical energy range from stationary energy storage (i.e., storage of the electrical energy produced from intrinsically fluctuating sources, e.g., wind parks and photovoltaics) over batteries for electric vehicles and mobile devices (e.g., laptops as well as mobile phones or other smart mobile devices such as smart watches), down to miniature devices for biochips, sensors, as well as "smart packaging" or miniaturized medical devices. Despite being essential in modern life, (some) batteries can look back on a long history-for instance, the lead-acid battery was discovered 150 years ago. Yet, the lead acid battery is still the system of choice for starter batteries in cars until today. Even the beginnings of modern lithium batteries date back to the 1970s. Recently, John B. Goodenough (The

Electrochemically reducing CO2 into fuels using renewable electricity is a contemporary global challenge that requires significant advances in catalyst design. Photodeposition techniques were used to screen ternary alloys of Cu‐Zn‐Sn, which includes brass and bronze, for the electrocatalytic reduction of CO2 to CO and formate. This analysis identified Cu0.2Zn0.4Sn0.4 and Cu0.2Sn0.8 to be capable of reaching Faradaic efficiencies of >80 % for CO and formate formation, respectively, and capable of achieving partial current densities of 3 mA cm−2 at an overpotential of merely 200 mV.

We report as traightforwards trategy to design efficient Nd oped porous carbon (NPC) electrocatalyst that has ahigh concentration of easily accessible active sites for the CO 2 reduction reaction (CO 2 RR). The NPC with large amounts of active N( pyridinic and graphitic N) and highly porous structure is prepared by using an oxygen-rich metalorganic framework (Zn-MOF-74) precursor.T he amount of active Ns pecies can be tuned by optimizing the calcination temperature and time.Owing to the large pore sizes,the active sites are well exposed to electrolyte for CO 2 RR. The NPC exhibits superior CO 2 RR activity with asmall onset potential of À0.35 Vand ahigh faradaic efficiency (FE) of 98.4 %towards CO at À0.55 Vvs. RHE, one of the highest values among NPCbased CO 2 RR electrocatalysts.This work advances an effective and facile wayt owards highly active and cost-effective alternatives to noble-metal CO 2 RR electrocatalysts for practical applications.Supportinginformation and the ORCID identification number(s) for the author(s) of this article can be found under: https://doi.
